More Abstract Surfaces

I'd like more abstract surface options to play with. The green-screen "add your own art here" are great, but I'd like a few more.

1. Reflective abstract objects. These planes, spheres, etc are mirrors and we'd be able to shove them around into other objects for the purposes of kit bashing.

2. Pure Void Abstract. Just abstract objects that use the "pure void" skin.

3. Bottomless Abstract. This object masks out the floor, so that you can lower things into it, or potentially create the impression of non-euclidean geometry. Basically DIY holes. :)

4. Transparency Abstract. This exports as a transparency in formats where applicable.

5. Doodle Abstract. An abstract that, when interacted with, yields some simple text and drawing tools, and then displays the results.
