CursorSpin

This makes the mouse pointer spin around and around endlessly! A little thing to annoy friends and family. This was made in about a week. It's simple and does not require any work to install, just download the extension, and it will automatically start rotating your cursor on most websites*. *Some websites may not work, and this cannot work over iframes (ads, sandboxes etc.). As well as this, this does not physically move your cursor - it only displays a rotated cursor. ————— Ver 1.6: Size can now be changed, with a more user-friendly slider.
