I've uploaded a couple of timelapse animations (or "WIP videos") to Youtube for anyone interested in seeing the stages my sketchcards go through. They're basically just built from the Work-in-Progress snaps I've been taking, but they show the progress effectively enough. There's a very short Lynda Carter one (I didn't take enough snaps) and an Amy Acker one so far - click here to take a look. I do intend to do these as a matter of course for my PSCs, so hopefully the list will grow.
All my old Work-in-Progress photos are still here on my Facebook page, and I'll continue to add to that album as I know plenty of folk can't be bothered with Youtube. (Moving pictures indeed - whatever will they think of next?)
