The FLARE100™ Art Projector sets the artist free, with a battery-operated projector in a size to go anywhere. The Flare100 projects a sharp image from as close as four inches from your surface all the way to mural size. Artists need never be without their art portfolio or client demos with the Flare100 and a flashdrive, or using the wireless screensharing feature with Android devices.
