Falling Sandroids
A mashup of Asteroids and The Falling Sand Game.
Fly your ship around with the cursor keys, build walls with X, shoot your gun with Z to pop bubbles.
When bubbles pop, sand will fall.
There is no winning and no losing, just chill out.

Has music! (but you can mute it and listen to podcasts or whatever. I don't know what you do, you do you.)
