Charcoal/chalk drawing timelapse

Timelapse from several sessions of a large charcoal drawing.

I took a photo every 2-3 hours, from the start, although forgot to take a photo on the final day before I framed the damn thing, so the video finishes on the neeearly complete drawing.

Photos are all snaps on my phone, so there's lens distortion and all sorts of nastiness going on.

It's not a how to or anything, just did it for my own interest.
