A few days back a very simple idea struck me right before going to bed. The more I thought about it, the less I could sleep. The day after this short night I fired up Photoshop and started writing a little bit of JavaScript. All this led to Fluid Corners.

The idea is pretty simple but could come in handy: when your OS's windows are moved off-screen, their essentials UI elements (think: buttons) stay at reach, sticking to the screen's limit. Go ahead and play with the demo, you'll get it!

Thoughts welcome, of course.

ps 1: A hot thread about it on Hacker News.
ps 2: @raphaelbastide's take on the idea: greasy!
