Update: moved to HERE.

One of my first programs in C#, a radial menu for launching programs.

Simply run the .exe, right click the system tray icon, add a few programs to the list then hit alt+space. Moving your mouse towards one of the icons will make it enlarge and vice versa, while moving your mouse away from the radial menu or clicking on something that's not an icon will hide it.

Radial Menu is 30KB and won't modify anything in the registry - all it will do is create a radial.ini in the directory you launched it from, so it'll work fine on a USB drive.

Radial Menu is free for personal and commercial use.

Problems:
Uses a crapload of memory, even when hidden
Isn't very CPU friendly when you move your mouse
Icons can look pretty bad
There's a control coloured outline around the icons/ring. I'm not sure how to get rid of these
There's no option to resize it so having lots of icons will be messy
Options dialog is incomplete. Will update it to let you rearrange icons, resize the radial menu, possibly change colours, disable icon resizing etc

Has only been tested on Windows XP 32bit.
