Controlling video frame/images by a photo sensor

Using Arduino Interfacing w/ Software on the Computer
1

In this video: Arduino test - YouTube
It it shown that you can control frames of images/video on the computer using a sensor and arduino.
But what else would I need to do this?
What software or code is necessary to be able to control the frames of an image like that?

I really want to figure this out, and the author of that video seems to have lost his code....

Thanks,

All that seems like is an LDR being read by the arduino via an analog input. The value read is then used to advance to a particular point in the video (probably scaled via the map() function before dumped to the PC via USB serial). See here for the LDR circuit and code for the Arduino:

Once you have the sensor reading, and dumping to the PC, then you need to write the code on the PC (using whatever language you want, but if you are still new to programming, and want to use something closer to what the Arduino uses - take a look at Processing: http://processing.org/) to read that value, and advance/decrement the frames of the video.
