Michael Wallace is a middle-school science teacher who lives in Baltimore. When he’s not teaching his kids about the Mesozoic Era (remember, “meso” means “between”), Wallace rides his bike around the city. Only, while he’s riding his bike, he’s also drawing something, using GPS tracking to trace his routes throughout Baltimore and forming them into different shapes, symbols that become fully detailed pictures. There’s “Jellyfish Invasion,” a giant jellyfish created over 16-plus miles and nearly three hours of riding, and “Gat,” a massive gun that took less than an hour over about 5.5 miles of biking. So far, Wally GPX, as Wallace calls it, has produced more than 100 pictures and doesn’t appear to be slowing down.
