Is this compressed sensing though? The description says "Sensor 30x30 pixels, 64 colors (ADNS-3090 if you wanna look it up)", so definitely not a single-pixel camera.

Sorry to get you confused. This is a different setup. TFA uses the 30x30 and no compressed sensing. The link above uses a single photo detector. They also use an LED matrix, but that's to make the _image_ (I think)
