We're two weeks into our Kickstarter (tessellation puzzles) with 3 weeks to go, and backers have slowed down. We're contacting science centers and pulling the stops on people we know to get the word out. Still optimistic. It's been a really fun project -- I've made friends with math artists around the world licensing designs, and then it's been a really tough process getting the designs to work into a puzzle that can be put together in a lot of ways. Got the samples from the factory yesterday, and they look great, so production is a go if we get the funds. mk and steve have backed the project already -- kudos to you both! here's the link to the project In other news, I joined a men's choir. They're a bunch of fun and funny guys, with a good sense of low humor. We sing all kinds of songs. At 51 years old, I'm the youngest by quite a bit. Going on a retreat with them this weekend.
