Explorer is a solar-powered art piece with a dynamically scaled frame rate, designed to conserve energy during those dark winter days. It gracefully navigates through stunning landscapes, from harsh mountains to rounded hills and stretched-out salt lakes. The graphics draw inspiration from the mesmerizing Mars-demo created by Tim Clarke, which flawlessly ran on a 386 processor.
Explorer's framerate is throttled by the amount of energy left in the 18650 li-ion battery. When it's fully charged it's running at one frame per second and it will throttle down to one frame per hour when the battery is running out of juice. Explorer will charge its battery using the two solar panels which can be rotated towards the sun using the gold-plated SMA connectors. The device lasts for more than one month in complete darkness and with sufficient solar energy it won't ever turn off. Explorer is available for purchase
