For anyone interested in yesterday’s photo-a-day, you too can make a geodesic dome from jelly tots (or a spaghetti bridge) by following the instructions under challenges here.

In addition to building the dome yesterday, I also drove down to Weston to trade my little Ford Fiesta in for an almost new Prius (Fiesta + bundle of cash = Prius). So far my mpg is over 50 compared to 40-45 in the Fiesta.

Many new toys in the Prius, including multiple cupholders in all sorts of ingenious places. My favourite so far – when you slide the cover on the vanity mirror open, the light above it turns on automagically. Now that is joined-up thinking.
