Clayworks 3.0 supports custom user skins; You design the graphics and tell Clayworks how to display it all via an as-yet-unfinished scripting language and you can totally change the look and feel of the software. You can also create custom tools bars enabling you to alter clayworks to the way you like to work.
At the moment, only the following skin is used. It's rather simple, a programmers test sort of thing.
I've designed some more complex skins which will be included in the final release.
Any good future user skins that are submitted will also be featured here.
