Ok... so I was playing through your games and I don't know why, but I decided to just place something on the Z key and let sifter2 run for a bit while I grabbed coffee. I came back 5 to 10 mins later to find my computer running some sort of industrial music beat in the background as all of the alcoves were vibrating with hundreds of little shapes. Totally changed the vibes of sifter2 into something way more avant-garde.
