not cool enough, doesn't actually show where the signal goes, just a graph of how strong it is

LED Representation of WIfi signal strength over a landscape via long exposure photography is cool.

should have got you to write my thread title :-)

Too long - wouldn't fit :P

Cool concept and vid.

Hey pinky - you know even if you can only "see" 2d, you can represent another dimension by using different colours..

Like say with that guy how he did his thing was he had 1 pole, and that pole only had 1 wifi receiver and 20 lights. That means between the access point and that receiver (where ever it was on the stick) those colours were being lit up, using a whole dimensions just to show where the reception was at 1 point in space.

But - if he instead had 20 receivers on that stick, and 1 light for each of them, say from green to red - green for good and red for bad you'd find yourself seeing at least 2 dimensions, meaning you can start extrapolating things from there anyway because you can see hotspots and cold spots for wireless reception, as he went past a car for example the wireless would probably get redder on only the parts which would be obstructed (don't have line of sight to the AP).

That would be really cool, especially if you went around and did long exposure like he did, and had a full (i want to say topology but that's wrong) wireless reception map. It'd almost be useful instead of just cool.

Anyway don't know how it'd solve your 3d over 2d directly - but if you can show something already in 2d then perhaps think about using something like colour (or time) to show another dimension.
