1) I Am Caltrain, a Google Map crossed with a map of the Caltrain (SF-bay area commuter rail) schedule and maps.
2) GMap Pedometer, which lets you see how far you’ve walked by clicking points in a Google Map– then counts calories for you too.
3) Three cool shirts at Threadless: a funny, nearly sold-out shirt printed with Blue-footed boobies, a funny and seasonally-appropriate shirt featuring a Batmobile which has lost a wheel, and one nifty artsy one of a woman bathing in a wheelbarrow.
