These logos are available for CUTwC-related content: publicity, merchandise, anything not bringing the Club into disrepute.
It is the experience of the web site maintainer that the idea of having something with a Club Logo on it tends to happen when there is not a convenient time to create one. This page is intended to be a central repository so that we have these designs in a suitable range of variations available in advance.
Technically, there is not really an "official CUTwC logo"; alternatives exist if you wish to consider them.
In most cases, follow the link of the image to access a download.
Very large or very small images are linked by text.
The text logo should be used where the name "CUTwC" is significant and where the association with tiddlywinks is non-obvious (where a more abstract logo would be meaningless). The colour version of both is obviously preferred, since it makes the wink stand out and contains the Cambridge Blue reference.
The "Tw" abbreviation may be useful as a narrower marker to complement the full name. It is probably too abstract to be used without the "CUTwC" logo providing context, but unlike the other designs it is clearly derived from the full "CUTwC" version.
The "pot made of winks" logo is more abstract, relies on colour, and particularly only has a CUTwC connection if combined with a Cambridge Blue glow — the "realistic" version is also pixel art and therefore doesn't scale arbitrarily (and high-resolution versions are large files; file sizes are shown in parentheses for this design). Despite this, it conveniently doubles as a "layered" image which gives it a mild visual pun for the home page link of the web site, and it's a more convenient logo shape than some alternatives; it's also got enough detail for interest viewed large, but enough distinct about the shape that it's identifiable at very small scale (making it work as a favicon). Note that, although the colours are a little dark because it's self-shadowing, lightening them quickly makes them look unrealistic; the current version is probably the best balance, after some experimentation. So long as full colour is available, it's a recommended option in situations where an abstract logo is appropriate.
The nature of the design means that different variants will be suitable for different uses.
The most basic approach: the Cambridge Blue glow in this case uses transparency in the image to allow the glow to fade into the background; this approach will not work for all situations, but is probably the most flexible (without knowing how the image is to be reproduced, it's about the best we can do, and generating a solid version on a specified background colour is fairly trivial from this starting point). The pixel art nature means that the file size varies depending on the amount of detail desired, with small files being pixellated/blurry when enlarged, and detailed versions producing large files. To avoid unnecessarily large files (and slow downloads or increased demands on computing/storage), please pick a suitable resolution — the web site navigation adaptively uses the smallest versions, for example. Other resolutions are available as favicons for the web site, but they're just derived from the 4800×4800 version.
Some places one might want to reproduce the logo use processes that may be incompatible with transparency — notably on T-shirts, drinking receptacles, etc. The following versions are variants of the 4800×4800 image with the glow effect reproduced as a half-tone pattern, which should work better in these situations (the fine half-tone for larger reproductions, the coarse half-tone for smaller ones). The assumption is that high resolution is suitable for print jobs, so smaller versions are not provided.
In some cases for web use, it can be more helpful to apply the glow as a CSS post-process effect; this allows better overlapping with other object, for example. Safari, in particular, seems prone to clipping the edges of the effect, so it's a bit fragile compared with integrating it in the image. Here, then, are plain images without the glow — to which the glow can then be applied in CSS. Without the glow, the "Cambridge" connection disappears; the glow is considered part of the logo, so these aren't intended to be used "naked". Again, please pick a suitable resolution to manage file size.
These use a Cambridge Blue drop shadow (tripled for density):
filter:drop-shadow(0px 0px npx rgb(163,193,173)) × 3, where n is shown below.
The bitmap art version is more "physically accurate" (it's ray traced), the higher-resolution files are large, and (eventually) pixellated. Where this is an issue, there is a (fairly) realistic hand-drawn approximation in SVG (vector) form; this will avoid going "blocky" like the bitmapped versions at larger sizes, although the inaccuracy of the highlights still starts to be visible if you look too closely.
Note that the the edges of the SVG glow effect are a bit rough, especially at larger sizes, due to calculation accuracy in the SVG renderer — this is more visible on some backgrounds than others.
To mitigate issues with the SVG glow effect, there is a version without it, instead using CSS drop shadow to apply the glow as described in the previous section.
While the pot of winks works best as a "realistic" image, not all printing processes support a full range of colours. In some cases one of the alternative logos would be a better option, but for consistency of branding, simplified forms are available. Note that, without the colours drawing the connection to winks, the polite objects that the monochrome ones resemble are some designs of bottle stopper, and they resemble... some other objects... as well, so please think carefully before using them and ensure that the context is obvious.
The "CUTwC text logo" above has sensible-looking lettering, a clear tiddlywink, and a little bit of a visual pun in the pot effect — it works as a stand-alone design. However, for plain text uses, it is a little tall, and this can be inconvenient; it is also "a logo" of itself, which is distracting as an adjuct to other designs where lettering (with some mild branding) is more important — such as adding a reference to the name of the Club to the Pot-of-Winks or Pot Rampant.
For situations that require wider, plainer wording (such as banners), there is an alternative design based on circles (hence a tenuous tiddlywinks connection); apparently Bauhaus/geometric designs are popular at the moment, too. The coloured version "works" only at larger sizes (like a banner) — it is too visually "busy" otherwise, but adds some visual interest at scale (like graffiti). Other versions work acceptably as text alongside a logo, since their design is more clearly textual and less graphical.
The Pot Rampant has been used as a logo since the 1980s. This was reconsidered relatively recently on the basis that it's not clearly associated with Cambridge and also doesn't scale particularly well. It remains appropriate in historical references to that era.
These logos date back to CUTwC events in the 1960s (notably ties and early Winkings World), and remain appropriate in reference to historical events. They presumably refer more to the excitement surrounding new-fangled nuclear energy than to the actual shape of a pot at the time. Unfortunately they don't scale to small sizes particularly well.
