I dont know if this has been discussed yet, but i just thought i would tell you a cute stupid thing you can do with a laser Pointer.
there is no suggestion to do this with these lazer GUNS yous guys have , unless you can do it safely.
get an Old speaker, tape a small mirror on the Side of the paper of the speaker, have the center of the mirror be resting in the center of the speaker.
now get your simple cheapo laser pointer (at least to test with
and align it to hit this small mirror on the speaker, so it misses any humans, and lands on the top of your ceiling.
now send your stereo speaker output, to the speaker. then spend about 2 hours adjusting everything.
the adjustement you want to make are to achieve a rectangular total area, instead of a LINE from the harmonics of the speaker.
angles, and mirror placement are very important.
once you achieve a large area, instead of a line, you will start getting cool things like harmonic circles.
it helps sometimes to remove the paper cone from the sides, some speakers will DIE, and not move at all if you seperate the paper off the sides. some will move much easier , getting you a greater level of motion of the mirror. just depends on the speaker that you got from the trash.
and to finalize this test, to show it to your friends, play "Dream Weaver" from gary wright on it.
they did this in a planetarium once, and (of course) we had to go home and reproduce it for Nothing. we had old speakers, pieces of an old mirror were easy to come by, and whats a simple laser pointer cost nowdays 5$?
so for about a MAX of 10$ you can create your own light show. and of course, with some of the lasers you guys got, you can make a "pro" light show.
i have seen the stuff with the mirrors and the motors that respond slightly to music, and if you get this aligned (including the mirror movement on the speaker) you will have a better show than they did.
