Originally conceived in the MIT Media Lab, this unique timepiece is built to count for 2,738 years. Use it to mark the beginning of your own epoch—when you get married, have a baby, quit smoking, launch a rocket, or on an ordinary Tuesday morning. Suspended in a durable borosilicate glass tube and sealed with gasketed aluminum end-caps, two LCDs show days, hours, minutes and seconds since launch. A funded Kickstarter.
