Sweatyboi troch Toadslick

This extension adds a toolbar button that enables you to choose between 'sweat' and 'glisten' particle effects for your mouse cursor. You may also choose to turn off the effects.

When the 'sweat' effect is enabled, then the more you move your mouse cursor, the more it will sweat! The amount of sweat will reduce over time as the cursor sits still or moves slowly.
