A periodic table I made with Inkscape for my sister as an birthday present.
I used the "Karisma Stencil" font from dafont.com: http://www.dafont.com/karisma-stencil.font
You'll need about 600x1050mm of vinyl foil for the black part.
If you also want to make one, it's pretty straight forward:
Download, resize if necessary (I cant guarantee that the small lines will still stick!) and cut it.
Place the small colored corners by hand after the black part.
