Does anybody else share my fond memories of chalking up the sidewalk outside your house on Saturday mornings? All the neighborhood kids would get together and draw pictures and play four-square and hopscotch. But the lives of kids today have gotten a lot more high-tech. They've got motion-sensing Wii's and touch-screen Nintendo DS's to play with, so you know regular chalk just ain't gonna do for their Saturday sidewalk olympics. They'll soon have the Dream Beam, a device that projects the game board for them...
