We got this kind of nifty sample of a Neopixel 'sheet,' which is uncut LED strips - the whole thing is flexible PCB material with a cuttable square pitch of 1 cm per pixel. it's arranged as a zigzag, so you can immediately use it as one strand of neopixel in a 12 x 24 arrangement. Or you could cut it into funky shapes and connect the data to data input between segments. the panel also requires 12VDC, but that's not too challenging; it could be useful when you need a flexible sheet in an unusual shape and don't want to piece together individual NeoPixel dots! Coming soon.
