We reported on UK-based Lightvert (Lightvert Has Large Displays… or not…) which has developed a system for creating huge LED-based displays on tall buildings that exploit the persistence of vision. Now, the BBC has made a video about the technology that is worth a look if you are interested.
Of course, people have exploited the persistence effect for a long time – the images below were from a company at CES, Kino Mo, and we have seen its demos several times – there is always a crowd around that is watching. The first shot used too short an exposure. The second one gets a better impression of the effects generated, but we didn’t have a tripod to allow a really well-judged exposure.
