I'll repost what I posted in the
Reach reference thread...
Here's a super cool link to a super cool glitch:

It's a rendered vid so you can watch it online or download it to your 360 for Reach's Theater. If you screenshot for ref, please share it here!!
For those who can't watch it for some reason - it's a spawn/death glitch on Boneyard Invasion where purple Spartans appear out of nowhere and die, and those Spartans are wearing nearly every perm in Reach, even the ones unavailable in the Beta.
And because I love to waste time, here's a nice collage I screenshotted and put together of all the helmets in Reach, I'll be uploading each picture as well as additional reference as I get time. The two at the bottom have no official names though I have seen unofficial names for them...
