I got an email from someone asking if Spout could be integrated into Alchemy, Alchemy is an open source drawing program and Spout allows programs to share opengl textures. Alchemy is written in java and doesn't use opengl for its graphics. I decided to integrate it as quick and easy as possible. I did this by importing Processing and the Spout library for Processing into the Alchemy source code and then, whenever Alchemy redraws the drawing canvas, passing a copy of the canvas to Processing and then to Spout.
If you would like a copy of the program just contact me.
