Fos is a wearable LED display system designed by Anders Nelson that shows an athletes heart rate and achievements. The lightweight and flexible panels can be programmed wirelessly through a mobile phone. The system weighs less than a golf ball and increases visibility while working out. Fos lets those around you know if you've reached your fitness goal, how many calories you've burned or who you are running for.
For every pixel there is 64,000 shades of light with over 60 frames per second processing power. The customizable system also has a 32 bit microprocessor, flash memory, LED matrix driver and an efficient power supply.
Anders Nelson is currently raising funds for Fos through a Kickstarter campaign.
