Dark Horse Comics (Buffy, Hellboy) and GelaSkins (those dudes who make reusable sticky skins for iPhones, MacBooks, etc.) have conceived and birthed a line of products to which all geeks will find themselves un-immune.
Hellboy, Buffy and a bunch of other Dark Horse IPs are now available in GelaSkin form (heck, there's even some Bettie Page thrown in there for good measure). iPhone skins go for $US15 while 13- and 15-inch MacBook/general laptop skins cost $US30.
You've likely seen the iconic art before, but that's alright. I could stare at Sarah Michelle Gellar's estranged cousin for days.
