Lightwave '09, Part II
I just went to a laser performance by Dmitry Gelfand and Evelina Domnitch. This was pretty amazing, but unfortunately I couldn't take photos. Here's a link to a video...
They have three colored high-powered lasers in red, green and blue, which is refracted and projected over a circular flat tray with soapy solution. When they manipulate the solution, beautiful textures are projected. There was a grainy texture, so I had to ask how they achieved that. They told me that they just densely packed the bubbles together, playing with the surface tension and properties, such as hydrophilic/hydrophobic surfaces of the bubble. What is seen is a visual and elegant light show, sometimes the light bubble film looked like peacock feathers. If you have an opportunity to see this show live, I highly recommend it.
