So a GIF (or PNG) of the time lapse, as well as a still image of the final frame?

I was thinking of something with a slider so you can find that diagram someone drew in the middle of a discussion last week.

You should see what Imgur has done in merging GIFs and WEBM videos. Every GIF has full video controls, including a slider and a play/pause button.

So basically if we just hosted the timelapse on Imgur...

We've made a board that can achieve the playback. Made a quick demo video of our first prototype. Would love any more ideas! https://www.youtube.com/watch?v=uxmVtfF6pIo

Since the data on a whiteboard could be vector based, something like a diffed SVG could work better.

MS already has something like this in OneNote, but I'm not sure how frequent the snapshots are. It's more of a revision history than a "watch every letter be written", IIRC.
