Last year artist Justin Maller created Helmetica, a sweet gallery featuring what he calls “busts of digital idols.” Just a few days ago he unveiled the sequel gallery, Helmetica II, which will soon be shipping in t-shirt form.

Personally though, I'm a little more excited that the "Chaos Clown" (Joker) and "Gotham's Champion" (Batman) designs are being sold as enamel pins. These are a much subtler way to express my nerdiness about the Dark Knight films, and they would look great on my laptop bag. I only wish more of the Helmetica collection were available in pin form. (Hint-hint, Justin!)

Get them for $20–$30 at Facets.la.
