Physics sumo where everybody is a circle, the only verb is shove, and the arena keeps getting smaller until someone falls off.

The screensaver logo in full screen, with a counter for how many times it has hit the corner while you waited.

Code-breaking tools and a cipher identifier for when you have a string of nonsense and no idea what it is.

Chuck banknotes into an open grave with the mouse, accompanied by an unreasonably committed soundtrack.

A chihuahua rotating to a dance track, which was apparently a complete website idea in 2013 and somehow still is.

The same premise with different flavours of damage — choose the format and how thoroughly you want it ruined.

The biggest browser arcade going, with genuinely decent HTML5 ports and a search that mostly finds the game you meant.

Translates a cron expression into plain English as you type it, then tells you when it will next fire. Ends a very specific argument.

Chain encoders and classical ciphers together and watch text transform between formats at each step.

Builds a gradient visually and hands over the CSS, including the awkward multi-stop and radial cases.
