I just concluded a really fun, rewarding Elance engagement in which I commissioned a project to illustrate and animate the 15-touch point-of-sale interaction that I described in this piece. You can see the results here. We'll put the results up on our home page later this week.
The results are meant to be self-explanatory, so I won't belabor the point here.
If you liked how this turned out, I recommend you check out my service provider, Light Within Productions (a.k.a., Ace Light). I had a really great experience on this project - my best Elance experience to date.
