Here’s a great idea for Summer parties – if you have a backyard, that is. Smarthome has some translucent floating globes that you strategically place around your backyard. They change colors somewhat randomly, and are powered by solar energy (they recharge during the day, then automatically light up at night). Unfortunately, they are recommended for use in chlorinated water, but they’d look great on a pedastal, in a koi pond, or as a table centerpiece.
