I'm attending more and more lectures where the projector and screen is being rejected for laptop, flash drive and large TV screen. One problem that has arisen is the laser pointers don't show up very clearly on the screen, does anybody know of one that will shine brightly?
I went to a lecture once where the person could change the laser image that appeared on the screen (could make it larger or a different shape for example)
I am sure if you look around you can find one like that.
