Projection mapping, whether performed as intricate alignment to surfaces or simply as a way to get out of basic rectangular viewing ratios, has potential to create a range of visual effects. Now, those capabilities are available to users of the fully free and open source, omni-platform goodness that is OpenFrameworks.
hvfrancesco has built a really brilliant, simple-but-effective, um, open framework for OpenFrameworks. It just does some simple quadrilateral warping math, and amazingly, it’s his first OF code. (In fact, even if you just want to learn that math, it’s worth a look.)
Full details on the OF forums:

Thanks to everyone who sent this in; keep the tips coming.
Expect more OF coverage, as they’re wrapping up a code intensive this week in Pittsburgh, and I’ve heard some very tantalizing news already.
