Glad you liked it. ;)
I've become a fan of Stargate before playing to Istaria and the first thing I thought when I saw a travel gate for the first time was "It really looks like a Stargate", especially the Dragons' gates that are constantly rotating : the Lunus one with the 9 red runes (movie and SG1) and the Helian one with the 9 blue stones (SGA).
This is one of the reasons why I haven't voted for changing the color of the portal, but for changing the ring color in Bristugo and Genevia, though I would make the blue ring a bit lighter.
