// Digital Chronophotography with (web)cam 1.0
// By Heino Boekhout | heino@odyssey.nl | http://odyssey.nl

// Instructions:
// Use the UP arrow key to activate light blending
// Use the DOWN arrow key to activate light blending
// Use the ALT key to activate screencapture every 30 seconds
// Images are saved in the project folder
// Change size(); for desired output, by default 640 x 480
