Bullet Time's a popular addition. There'll be N different bullet time mods by the time Vegas is done with. So why not skip the other N-1 and go straight to the end?
Bullet Time N gives you a hotkeyable item you can use to trigger Bullet Time, intended as an alternative to VATS. During Bullet Time, NPCs are slowed by one amount- default 75%. The player, however, doesn't have to be slowed by the same- default player slowdown is 50%. Until your action points are all drained, you'll be going 2x faster than your foes. These %ages are user-configurable, so if you don't want a speed bonus over the enemies you can remove it- or you can make yourself even faster.

It includes a couple of Challenges for killing foes in Bullet Time- kill enough, and in fancy enough ways, and it'll be more efficient and effective.
There's also a variety of visual effects, ranging from the bizarre colour-inverted http://www.newvegasnexus.com/downloads/images/35085-1-1287865373.jpg look to tinted, monochrome or blurry. And more to add...
In an experiment with user contribution, if you've got a visual effect you'd like to see as a bullet time option, make a .esp with it in, post ITT and I'll add it to Bullet Time N.
Any other questions, comments or feedback are welcome.
