Just have to tell my friends as I get excited when I do something that actually works. This is a system I developed for a McDonald's restaurant in Australia. It uses a Canon DSLR camera to shoot photos of kiddies coming down a tub slide located in the Play Land area and displays them on a 50 inch TV for the parents to goggle over. It is triggered by an opto sensor in the tub slide and rotates the last 4 photos on the display.
We are still tweaking the display size and shortly it will fill the TV screen but that is minor in retrospect as right now I'm just excited it is installed and working. A few photos the customer sent me.
