Simply blow on the speakers to make it spin. The harder you blow, the faster it spins ***It may be laggy on certain browsers*** (Look in notes and credits for more tips) Curated 9/2/2013! Thanks @jkl0l :D
Extras: If you blow at about half speed it will change colors If you blow at top speed it will fly off and come back (you have to blow VERY hard or blow very close to the speakers to do this) Turn off/on the extras using the on/off buttons This uses the "loudness" block to set a turning speed of the pinwheel by how hard you blow feel free to remix (AS LONG AS YOU CHANGE IT IN SOME WAY!), just give me credit for the original. Have fun and make sure to click "love it"!!!
