Put the brakes on boring. Blik, a Venice, California, design firm that makes decorative wall decals has just introduced a line of removable PVC stickers expressly for cars. The ultrathin graphics stay on through rain, sleet, snow, and car washes—and they won't ruin the paint job. To remove: blast with a blow-dryer, and they peel right off. This Ford Freestar is decked out in Blik's spheres; other zippy designs are in the works. Now kids don't get to be the only ones with hot wheels. 866/262-2545; whatisblik.com; $10 to $50 per set of one to eight.
