ok, i have a couple built, and I'm going to try to get pics up..
i used square acrylic tubing from us plastic
i used bare metal floral wire from Michaels
i used a large amount of LED's that i bought from China
i soldered the positive side of the LED's to the steel wire and the negatives of each LED, i used wire wrapping wire.
i placed the LED's about an inch apart on the steel wire.
then, i fit the whole thing into a piece of square tubing.
running cat5 cable from the conductors (including the steel wire) back to the Freestyle.
the 7 LED tub takes 2 ports on the dreestyle, the 15 LED Tube takes 4 ports.
the nice thing about this version of meteor tubes, is that each LED is directly controllable by the sequencing software.
