I took a look and didn't see any element to show video (real time video streaming? showing a webcam demo maybe?) which I find like an interesting application. Making GUIs is always a fair amount of work/overhead on whatever you are working on, and I like to stay in Python when possible (I've used REMI (https://github.com/rawpython/remi) to create web apps before in Python). Thanks for creating this. I look forward to updates!
