From what I can tell, you draw on that little section of the tee, and can then light up your message using an attached battery pack. I can’t really think of a decent use for this beyond novelty. If it could be possible to have a much larger ‘canvas’ which looked more naturally like part of the tee (rather than having a frame around it) then I think this could be a lot of fun, possibly even useful to artists who wanted to prototype designs. Imagine if you could plug in a memory card and it would scroll through several different designs automatically. Obviously, that’s a bit ahead of our time, but maybe when I’m a grey-haired, old t-blogger they’ll be commonplace.
Ive just had a thought for a DIY version of this, just glue an Etch-A-Sketch to a tee and carry a torch around. Much cheaper, and you’ll be able to make countless nipple-twiddling jokes!
