Got a great transition effect for swapping background screens in a cool and groovy manner? Then showcase it here! The only rule is that the transition must allow the background to change in a smooth manner.

Post your request to be added on the comments page.

I was inspired to make a (silly) transition effect when @colinmacc mentioned creating a (not silly) one for a game he's working on and @kriblo and @papipupepappa followed suit by also creating cool (not silly) ones.
