A viewing mode where you can see an event from the point of view of one of the pixels.
You click on it, press a viewing direction (or arrow key), and see what the pixel is seeing.
For example, say you make an explosion. Click on a space, point towards the general direction of the explosion, and see the wall of fire barrelling towards you as if you were in that space.
An unfixable limitation- It will always be as a straight line, since TPT operates in 2 dimensions (as how we are 3-d, but see things in 2-d, which is why we can replicate visions with pictures). However, brightness and relative size (as how a lamp near you seems bigger and brighter than a lamp far away) can make this alright.
It would look amazing.
Sounds hard as CRAP to code, nigh impossible.
But, it IS a cool idea.
Maybe, instead of anywhere, you had to be a STKM or STK2!
EDIT:
It would be a whole different game.
