Algodoo

This is an updated scene to my earlier version. The updates are as follows:

1. Movement of the partition is no longer done via lasers.
2. Instead of using flashing dots, I stretched the dots vertically so that they are now elongated ovals. I did that in order to make it easy to mask different areas of the flashing ovals so that you can see the difference between having them in front of a black and white background and a solid gray background.
3. I added a feature that allows you to make the partition invisible so that you can mask the shapes with your own hand in case you think that the scene "cheats" some how.

This scene is a very good illusion (just like LIFE).
