--- title: HelioDisplay Projections on Smoke: Second Look — HIGH T3CH url: https://hight3ch.com/heliodisplay-projections-on-smoke-second-look/ date: 2006-07-27 --- # HelioDisplay Projections on Smoke: Second Look This is the second time that I am posting about HelioDisplay on High T3ch. Remember the projections on smoke that seemed like the perfect sci-fi dream-come-true? The first post did not have a very detailed video so this one features more of the technology and you see it from all angles. Now we are even aware that it costs $20,000 USD. VIDEO->
