After a wildly succesful Kickstarter campaign the Spark Core (http://spark.io) is now shipping. I got mine last week and here are the first photos. Really nice design and the protoboard is an added bonus.
I'll keep posting more when I get time to dwell into these.
I was changing my filament from black to white a while back and somehow the nice smooth change from black to white caught my eye. Since then I have been wondering if one could use this method to print with unlimited shades of gray or even unlimited colours to create a full color 3d printer.
