Without the invention of the wheel, the skateboard never would have evolved from its water-ski ancestors. Glide across vast stretches of town with today's Groupon: for $25, you get a graphic design skateboard deck from Graphic Image Skateboards (a $49.99 value). The deal is available online only.

Graphic Image Skateboards provides performance boards with original artwork by professional comic-book artists. Skateboard decks are crafted from a loving and psychologically balanced marriage of seven plies of hard rock maple and high-resolution graphics. Skaters catch air and compliments on decks sporting Top Cow Productions images and other designs such as the ammunition-bandying Bomb Queen, bone-bundled Witchblade, asphalt-defacing Savage Dragon, or minion-rallying The Darkness. Graphic Image also receives originals from marker masters at Image Comics, Savage Dragon, and Marc Silvestri.
