So if you've not seen the Wiki recently (you should be disappointed with yourself.

), you may have noticed some of the replacement high-ish definition
Dimetric-renders of most of the blocks in ComputerCraft -
Computer,
Advanced Computer,
Monitor,
Advanced Monitor,
Disk Drive &
Printer (image links). I also put together a
portable image-format keyboard of all keys and their associated key codes in ComputerCraft.
Most of the rendering done above is done in Java - for dimetric rendering - and PHP for keyboard rendering (personal preference). I've thrown the code on Github
here if anyone's interested in reading some pretty, err, messy code and learning a little about LWJGL/rendering methods/etc. I would have included the images here, but they'd distort the page pretty nicely.
(Next project: turtle rendering, woo!)
