Wild Cards

Everybody seems to have an old card deck lying in some miscellaneous drawer in the house. Rather than your millionth game of Go Fish or pulling that trick all your friends have already figured out, construct a colossal creation with these card clips — they even come with a deck of cards of their own! Taking the house of cards of yesteryear to new heights, the sky's the limit on what you can design with a single deck—or seven! Perfect for any card shark — or anyone looking to make a shark out of cards! — these wooden clips allow cards to be attached at almost any angle, so you can contort them any way you choose. Clips made in Mountain View, California.

Marshall Grinstead is a mechanical engineer who's worked on everything from bomb disposal robots to cell phones, but he began his toy-design career at age eight, when he started looking for a way to make card houses that wouldn't fall down. With help from some college friends, he created Skallops, a creativity-enhancing construction toy. Skallops let kids and adults alike intuitively learn concepts like trusses and bracing from engineering while creating their card sculptures. Skallops have been featured in design blogs including Core77, AIGA, and WIRED. "I love inventing things that are simple and elegant in design, but limitless in application. I hope kids have as much fun building with Skallops as we did creating them." - Marshall Grinstead
