Capster Alternatives, Similar

Capster is a nifty app I created for OS X, based on the idea of CapSee , which notifies the user when Caps Lock is pressed, to help with accidental misclicks. CapSee is very useful, but it had two flaws. It was a bit slow, and I really, really like using Growl for notifications. Enter Capster. It is as fast as can be, and replaces the Bezel type of notification CapSee uses with Growl. It sends a notification on startup, and after that, one every time Caps Lock is pressed. It is released as open source under a FreeBSD license, and the source code is hosted on GitHub.
