This passive flexible proto-PCB is about large as a piece of paper, but instead of dead-trees its made of very thin FR4.

We're not bending the truth! This protoboard is only 0.4mm thick, so its extremely bendable and you can cut it - just don't use your nice fabric scissors since the fiberglass will dull them. It has a bend radius of about 2 or 3". You can also crease it, but that might break a trace if you crease a trace, and of course it may crack and break along the crease.

And, of course, there are 0.1" spaced prototyping holes with solder pads. They aren't fully plated through, the holes are only on one side. But, you can solder any thru-hole components to the pads. Sensors? LEDs? Jumper wires? We have no assumptions what people are going to use it for, but we know it is going to be awesome.
