That's why the main image represents a portal..."teleport".  A lot of time and effort was put into this by the non-core dev team, and I'm pretty happy with the final logo we've developed.  We've moved away from the "coin" image that everyone else seems to be stuck on.  Our logo represents a portal in abstract form and will be easily recognizeable, and is perfectly scaleable, so it is very to make out even at small sizes.  Another aspect is that the gold logo will be the main logo, however we can use different colors for different features, e.g. blue for teleport, green for privatebet, black for anon card, etc.
