Utterly gorgeous.

What is causing the vertical rippling - a bit like rising smoke - through the straws?

[mtbf0]

aw, jeez. your favorite feature is a video artifact. sorry.

[HD41117]

Heehee. Not at all. The two paragraphs were not linked! I thought it might be the video.

I reiterate: utterly gorgeous! When I get a moment or two I will attempt to find out how you did it.

ok, so i guess i can't put a url in a comment, but if you search the forums at ladyada dot net for blingM you'll find a posting about the first bit of code i wrote for this project.

Thank you very much for the pointer. There is a lot to be gleaned from those posts.

Ah, PWM... lovely. 8^)

I feel compelled to show you something I made. Please "search everyone's photos" at Flickr for Solar Engine 2. The two HD41117 photos are mine. Freeform! Yay!
