That's a pretty good idea but 1m of that is 40 USD.
Also the LEDs are 1.7cm away from each other (8 every 13.6cm. 32 is over half a metre long).
So you'd have to make a large scale POV wand. Not so good for (say) embeddiing in a bike wheel but great for a big hand waving wand or for large scale light writing... ooh thats a good idea...
I still vote for the shield though
