Okay, maybe it's not entirely practical, but I like this sketch drawn by commenter ROM for the recent contest to design a superhero costume for Sam Adams:

ROM (aka "Ryan GTG") also has a bunch of funny comics up over on Tiny Mixtapes—his newest is called "Innovations in Tip Jar Technology," so, you service industry types might want to check that out.

[If you are a commenter doing interesting creative things* feel free to email me and we'll spotlight 'em on the blog. Unless I really don't like whatever it is you're doing, in which case I will pretend your email got caught in my spam filter. Does anyone believe that line? Ever?]

*do I HAVE to specify non-pornographic? probably, huh.
