I'm looking for a laser pointer or other method for drawing people's attention to a particular area or item on a large LCD screen while it is showing a computer presentation (PowerPoint) or other computer display. A standard red laser pointer does not show up on the screen - the light is absorbed completely. I'm wondering if a green laser would work any better, or if a more powerful red laser would work. I don't want anything powerful enough to damage the LCD panel. Green lasers cost about five to ten times as much as red lasers. Blue lasers are also available, but they are extremely expensive. If anyone has any experience with green lasers, or any other product that might be useful for this function, suggestions would be appreciated. Thanks.
