Over the weekend, while researching ways to combine cocoa and openframeworks I stumbled upon this sweet simple code to grab the pixels below an openframeworks app. Thinking of what to do, I dusted off my old ofxHalftoner* to dither the content of the screen and to my surprise everything worked reasonably fast in real time.
I also recorded some video. The quality of the dithering is poor due to the video compression, but you get the idea.
And then over a docu about the opening of an op art exhibition from the 60s published on ubuweb, which seemed totally appropriate.
While writing this I’ve seen that creative apps has written about it, which is very flattering for a quick hack. Thanks!
