If you have an intel mac at home, chances are you have photobooth, a webcam application that allows you to take pictures of yourself and also add some effects. In the linux world, photobooth = cheese. Cheese is one of the best apps I have seen in a long time, the design is nice, the effects are even nicer, and best of all you can record videos! To install cheese, follow the following commands.
1. Pop open a terminal and enter the following commands:
sudo apt-get install cheese
Note: You will need the universal repo enabled.
2. You can find cheese in Applications > Accessories > Cheese
Simple as That! Below I have a video demonstration of cheese (that I made 
)
