Window Animation: Moving stained glass window.

This is an offshoot of some work I am developing for the possible Virtual festival and I’d like to use the LightWindow project as an opportunity to test some ideas. I want to test projection mapping a live website onto a surface such as a window, rather than rendering the animation as a video. The content will be a live website running off mini PC connected to the projector. I will make an alpha mask and load it onto the website to map the animation to a section of the window as per below.
