@kenj suggested a feature I too would enjoy very much, a parallel programmer for the Blinks (it will be great to quickly have the same code on all Blinks).
While there are devices made for gang programming, we didn’t make one for Blinks. I can think of a handful of instances this would be useful, but I think we are going to satisfy the main interest of this when we update the Blinks firmware to share games via IR. This way, your Blinks will be essentially programming in serial ( actually a bit more efficient because of the 6 faces of each Blink).
In house we are testing the final materials and form factor for the commercial Blinks, which will determine a final IR protocol, informing the way games are transmitted to each other. This is an important feature and one I am excited to have in development. I am curious to hear your thoughts on this and @bigjosh will surely be interested in discussing implementation when the time comes.
