Select a frequency and see how trigonometry works. Plus, you'll also be able to hear that frequency, isn't it magic? Press '1', '2', '3', '4' to change colours and set markers.
Getting Unstuck 2020, day 3. There's almost nothing cooler in the world than waves, so when I started thinking about two sprites that were not doing the same movement it came to my mind that, sometimes, two different movements can be just the same if you look carefully.
