As our project got underway, we ran into some bumps on the road as well as encountered some unforeseen circumstances in the prototyping phase. In particular we found a few key insights: (1) ink comes off of acetate really easily (2) lateral motion looked better than a dragging motion (3) weights were required to get the proper movement and prevent the acetate from bending.
You can get a sense for these issues in the video below.
Is this a good/useful/informative piece of content to include in the project? Have your say!
