You have to get approval from pargo@lanl.gov - he's the organizer. It's
being held in Santa Fe this year, at an artist's colony. May 4-7. Not much
else for details!

I like to announce the some what premier of my web
page. Not fully completed but still has some pics.
So check it out and tell me what I can do to make it
better.

I have made what u call "fireflies". They are
actually called pummers(charge all day shine, blink,
etc... all night) in the BEAM community. For mine I
have used the old D1 SE connected right to a LED for
continious lighting. But if you want it to blink I
have used both a FLED in place of the regular LED.
And attached a Bicore with 2 LEDs so they alternate at
night. But if u want just one LED to blink just use
one LED. Also instead of using a D1 SE you can use
Wilf's SIMD1 which I haven't tried personally but have
heard good results from it. Hope this helps ya.

13254 Saturday, April 08, 2000 11:53 PM Re: Wacky ideas floating around beam@sgiblab.sgi.com Timothy Flytch i think one side is mirrored while the other side is only partly mirrored.
the light bounces back and forth until its coherent and exscapes out the
partly mirrored side. coherent means all the particules of light are going
straight in 1 direction, incoherent means its going everywhere
