They look a bit loopy since I made them in about 10 minutes each (and its about 1:05 in the morning), but they'll look great when I scale/chop them down to a usable size (probably later today, I need to sleep). Feel free to comment on how misshapen the moose is or how wide the bonds on the molecule are.
I didn't know that Inkscape could export transparency. I'll have to remember that.
