I’d like for you to create a video clip using the built in video camera on your iMac (use photobooth) and import it into GarageBand.  Once you have it in GarageBand I would like for you to replace the audio with loops, sound FX or anything else you like.  Also add 2 photos to your video.  Once you are done, export your video and save it on your desktop as your name.  Click the movie file and press Command and i to get the information of the file.  Leave a comment with the size of the file.
