My new Indiegogo campaign launch has me pondering portals. I found this clever collection of elevator doors optical illusions at VisualFunHouse.com. Click images to enlarge.

Some elevator doors open to reveal a delightful surprise on the back wall of the elevator, others use the action of the doors to create their special effects. Stimulating creative ideas here!

A good thing the images talk for themselves and don’t need an elevator speech, because I am knee-deep in the new campaign video that gets uploaded this week via the YouTube portal.
