I would much prefer something like this for the Gold-Pressed Latinum Store.
This. Would give more point to the GPL currency.
You already use it to buy pretty things to put on your mantle on board your ship, or make your ship look different with the holo emitters. Using GPL to pretty up your transport beam fits in nicely with the 'social currency' idea of GPL.
Whats the transporter effect with the spirals in it. Thinking bajoran/cardasian. Would be neat too.
I use a program at my job called Particle Illusion that has several authentic recreations of various transporter effects meant to be composited onto live footage. If interested, I may be able to kick a few vids and post them on Youtube or Vimeo.
