harpia: simple way to explore opencv

I just discovered Harpia. It is a graphical block diagram interface to allow experimentation with opencv libs.

The nice thing is you can hook the blocks run it and see what it does, then you can generate C code. This code is good for seeing how to interact with different opencv functionality. Of course, bits of C code can always be pasted into openframeworks projects too. Different settings are easily changed too by modifying parameters of the blocks in the block diagram.

If you are running ubuntu/karmic you can install from repos. Windows install seemed old, I didn’t try it.
