I’m sure many of you would have seen this video by now or a variation of it. It takes a very basic concept of a long shutter exposure and some light. Today I downloaded a cheap app which does the same thing for the iPhone and iPad. It’s called Holographium and it can be picked up from the app store for $1.99! or free if your iPhone is jailbroken.
I’ve only had a brief play around with it but here’s the 2nd exposure I did for the night, I think it turned out pretty well, which is a good indication on how easy it is to use. You can control the density of the light, width, colour, text and duration which gives you an ability to make the text appear however you want! I’m sure someone who is creative enough can produce some amazing typography.
