Fun with light effects (gs1)
 

Some simple trigonometry and light effect placement can make for mesmerizing displays! Enjoy!

light-scope.nw is a way to indicate a player's health using a sine-wave type display. The wavelength changes in frequency and color along with how many 'hearts' of health the player has left.

(whoops, I thought I posted this in the code gallery .. can someone please move it there?)

Looks cool D:

Quite cool. I like the hallway one best, though to be honest, almost all of these are too distracting to ever be used in game (however, I think these are meant to be the center of attention, not to enhance a level, so that's not really a problem).
