	CG animation "Heaven" by Bobby Crotty
Bobby, St. Mark's class of '02, was driven to bridge the gap between the technical wizardry of digital imaging and the artistic applications of these new tools. While he's wasn't working on his AP heavy senior track, captaining the cross country, swim, or track teams, he was working on improving the state-of-the-art of these tools.	A java applet of the animation is supposed to load here.

While taking the IOngineering class in 2001-02, Bobby pushed the envelope on what high school students can do with Digital Signal Processors. Working with Texas Instrument's DSK-31 board and Hyperception's VAB software, he has developed some novel applications for the digital camera.

The first project is the first reliable, real-time CCD camera-based change counter made by a student to come out of the Infinity project. Here is an image of the programming blocks used to identify each of the coins under the camera and then assign values to each of them. The screenshot below shows how the problem of counting change in real-time was accomplished.

The second project was based on the need to design a system to increase the security of the campus. A motion-activated movie recorder was the result of Bobby's work to preprocess the video signals to ignore minor fluctuations in the background. This intruder alert system sounds an audio alarm and records a digital movie of any motion it detects. A QuickTime movie of the motion activated tracker shows how sensitive the crosshairs are at targeting and stabilizing on the motion within the camera's field of view. This project then developed into a hand operated "Air Guitar" based on the optical tracking used in the intruder alert system.

The third major project is one Bobby helped lead in December 2001. The Digital Worlds Project will create fractal planets and universes to create rich and interactive learning environments for students learning earth science and astronomy.

Bobby's digital art projects ("Dante's Inferno", "Campfire", and "3-D sample") used 3-D computer graphics programs to generate the movies that can be found below:
