-As of 20.8.2012, we have 20 LEDs hooked up and working, connected to blinkenlight computer, with good prospects of getting the rest working too. You can control these LEDs over the LAN, see roadmap for details for now.+As of 20.8.2012, we have 20 LEDs hooked up and working, connected to the sargon computer, with good prospects of getting the rest working too.
