Tessellation

Ok, so this is way over my head and I need to learn fast.
I’m curious as to wether tessellating shapes in flash is doable. This will be only quadrilaterals. The idea is to create a zooming gallery (silverlight-esque) where the older an item is the smaller it gets.

The smallest piece of advice is welcome.
Thanks.

p.s. It doesn’t have to be neat or aligned to a grid. So I may just use some sort of physics based thing and allow a bunch of shapes to fall together.
