How were you implementing the Canny edge detector? As a GLSL shader or on the CPU?

I implemented a (simple, not quite Canny) edge detector in GLSL and it runs fast enough not to be distracting (https://github.com/matt-williams/Optometrist).

I've tried using OpenCV (which isn't GPU-accelerated on Glass because I think OpenCV is only accelerated on Tegra) - this _was_ too slow.

Yep, via OpenCV. If I still had access to Glass I'd love to try out your library. Do you have any first-person videos of your application? If you have an iPhone 5 you can hold it up to the prism in good lighting and record first-person (it's a real pain though).

I don't have any first-person videos yet, but I should give it a go. (I don't have an iPhone 5, but I can try with my HTC One X.) I'll link to it from the project's github page.
