# Lights This example demonstrates powerful Porter-Duff composition used to create a nice noisy light effect. **Use W and S keys** to adjust the level of "dust". The FPS is limited to 30, because the effect is a little expensive and my computer couldn't handle 60 FPS. If you have a more powerful computer (which is quite likely), peek into the code and disable the limit. Credit for the panda art goes to [Ján Štrba](https://www.artstation.com/artist/janstrba).
