So in my metals class I need to make a table. I got the idea of drawing up a symbol in AutoCAD, and cutting it out of a piece of sheet metal using a computerized plasma cutter. I think doing a biohazard symbol would be pretty cool, and I already drew it up, but maybe one of you can come up with an even better idea?
Here's what I made for all of you who aren't familiar with it.

Also you have to think, I would be removing pieces which means it would have to work in a way that it would all stay connected. Can't be too detailed either; the symbol needs to be rougly 2'x2', and the cutter makes cuts at about 1/16" thick.
