We just opened pre-orders up for blink(1) mk2, our awesome USB RGB LED notification light. We're still fulfilling orders to our Kickstarter backers, but we expect to get all them out before June. Then we'll start shipping pre-orders. So if you'd like to pre-order your blink(1) mk2, visit: http://buy.thingm.com/blink1
And if you want a blink(1) mk2 before then, join us at Maker Faire! We'll have a few for sale there.
It's super small, about as big as your thumb, but bright enough to be seen across a room.
The blink(1) mk2 has two independently-addressable RGB LEDs, so you can assign different events to different sides of the blink(1).
