So our foriegn friend is looking for a custom etched difraction type head for a laser ?
That may be a bit tougher to locate. All I can say is that a few years ago I spent $5 at a dollar store and got another cheapo red pointer with about 30 different graphics heads.
Still have them in a plastic bag. One day I will hook up dozens of these little cheapies each with there own graphic and hopefully get the computer software to control them, with about 50 other lighting items (both low and high voltage) and a RGB scanner WHILE playing the music it all goes to.
If you're gonna dream, dream big !
Good luck Yeori. If you find out where and how try to post it back here, OK ?
