is the cefn kaleidoscope screensaver still up for download? cant seem to find it:(

I am helping design a large kaleidoscope that people can walk through and participate. I found your video, and will try to download and see if I can project this image onto a large area of broken mirrors, in a huge tunnel like installation for New Years First Night Celebration in Monterey, CA. Any suggestions? Kira

The Kaleidoscope transform means that one sixth of the picture (a triangular section) gets duplicated six times around the central point. With the video feedback, (camera filming it's own projection) that means that it becomes six times six times six etc. up to infinity. Hence it makes a fractal from the shadow Dave casts onto the camera's detector, by standing between the projector and the camera.

nice...

you are wonderful and brilliantly inspiring. Once weve sorted a proj well give it a go. Thanks love.

I've imagined something like this before I've ever seen your video. The dance is new to me but I guess it comes naturaly when you play your favorite trance song and stand in front of the the moving mandala. I wonder how four or five of these would rock a psytrance party here on my town. Man, I would love to live nearby and take a look at your works. peace bro!

Happy to talk you through this installation. Needs at least one projector and a reasonable camera right now, as well as a Mac with the developer tools installed.

If you want a Windows/Linux box to run it, I can talk you through the software you'd need to install.

There's also an OpenGL/Python version based on Pyglet in the works which eliminates the need for literal video feedback (emulates feedback through pixel textures). This will have to wait though. No time right now.

@cefnhoile awesome work! can you tell me the windows software that'd do the kaleidoscope effect?

[cefnhoile]

You can download the screensaver which works with the Mac by searching for 'cefn kaleidoscope screensaver'.

Once it's installed, just point the camera at the screen!

Works best with a projector and regular zoomable video camera on a tripod.

That way you can adjust the relationship between the Kaleidoscope transformation and the scale of the screen and yourself in the picture.

Good luck.
