i see junfans got some pics up aswell, so here are some more!
my ultimate flash was working on a particle accelerator when he [or she, there are too many men in the jl] has to get close to the particle accerator, making the character's atoms spin faster, thereby allowing superspeed, but also causing accelerated ageing, not to mention the fact that when the particles go so fast, they cause EXTREME heat. luthor designs a suit to contain flash, with heat dissapation vents, which light up with nuclear energy, thereby allowing for "lightning" to come off the suit. in this pic flash is going so fast, his atomic structure is sufferin', which is why he's seethrough.
