Raspberry Pi (Zero): a computer about half the size of a credit card and the brains behind a lot of our robot, sound, and light creations.

Poi: a small light ball of woven flax, swung rhythmically on the end of a string in Maori songs and dances.

Combine the two and you get a spinning light show that uses persistence of vision to display images in thin air.

At least that’s the theory and we are at stage 2 of finding out exactly how awesome it will be.
