Actually I made them... They are related to that topic, that's where I got the inspiration. Originally I just made a picture of how I would imagine the beams should look like, and it kinda got out of hand...

You can download them from here if you want to give them a shot:
High resolutionMedium resolutionInstallation instructions included. The VP replaces all beams with my textures, and should be used as own mod activated before mediaVPs. Oh, and the beams are animated, which naturally doesn't show on screenshots.

As I said, some beams still look a bit strange (too much tiling factor most likely), but they work, and many of them actually look very good most of the time. High resolution slowdowns are negligible on my rig (AMD64 3200+, GeForce 6600, 1024 MB DDR-SDRAM), so I use them, but medium-resolution ones don't look too shabby either.
I personally like the AF-beams the most of the bunch, and the Vasudan yellow beam is the second best in my books. But most other beams work fine too.
