LCD zoetrope tests
A test using a circular array of smartphones - to find out if zoetropic motion is possible with LCD screens. Findings:
- It works
- The limited viewing angle doesn't seem to be a problem
- When viewed in the dark the screens seem to 'float' mid-circle
- The screens reflect into each other, better use non-or-less-reflective ones
- In a dark environment the screens cast beams of light on the surroundings
- As with a regular zoetrope, images get slightly squished horizontally
- This test should be repeated with just iPhones, set on the same brightness, and using thinner slits.
Shadowplay tests
Makeshift setup:
Displays for a possible display-based zoetrope
E-paper
E-paper would be great, as it's thin, viewable from a broad angle, has a high contrast and a nice texture. Pervasive Displays manufacture e-paper displays, one of their offices is located in Soest, The Netherlands. They don't sell it, sadly. The cheapest/nearest reseller I found is Ineltek, in Heidenheim, Germany.

Taking apart a broken e-reader to see if it's possible to do something with the screen.
Running electricity through the connectors randomly, it didn't work as the voltage was too low. Also, the touch screen seemed to be inseparable from the e-paper screen.
A recent discussion about e-paper on the Arduino forums.
Perhaps an alternative would be to buy a bunch of cheap e-readers. (These are sold out everywhere.)
