 Okay, so yesterday on Carousel, we bought this very, very nice fan and because we thought if it's possible to just display an image on a rotating fan. So what we effectively did is we mounted an LED strip on one of the blades and then did some math and calculations to check that the frequency is correct so as you see it's not working yet. It was supposed to display an image actually but it turned out to be like a random pet touch generator. So effectively the microcontroller inside is connected to smart phones so that you can adjust the frequency of the of the pattern and then also can do some random stuff actually. So you can try to click around a bit. You can just try to make it stable. Okay, that's it.
