Basically a sub forum for only you
Is there something wrong with that ?
But in all honesty, there actually isn't any good category to post these kind of things. I would probably opt for something like "applied graphics", "generated/procedural graphics" or something (thogh the graphics subcategory is good enough to me for now).
Using the component/package as a lead is not really the solution either. I make these example (also) work with/for PTC and/or SDL and it would be possible to do the same for any engine/package that does anything remotely with graphics.
