BabyProof makes your machine toddler-proof, while still allowing you to watch a movie, or chat with relatives via Skype. BabyProof prevents key and mouse presses from reaching the computer, while letting you run the app of your choice. Start up an app of your choice, then switch to BabyProof. BabyProof doesn't obstruct anything on the screen, but captures all mouse and key presses to prevent them from affecting the running program. Type your own special "quit" word to exit out of BabyProof.
BabyProof can also be used for kiosk machines. Start your full screen kiosk app, then launch BabyProof. You'll be able to prevent all access to the machine via mouse and keyboard while your app runs.
