@Prinz Eugn: Awesome stuff! I like all of them, but I personally think #8 is too... EA. Anyway, I really like them.
To put a spin (pun not intended, but now that I see it, I intend it) on some of it, what if the G was rotated to be a standby button? Here's a few examples:
Of course, all I did was rotate these. A proper "standby button/G" logo would have to be manually made to make it look super awesome...
Edit: alternatively, you could do an actual standby button, but rotated to be a G (of course, it might need to be stylized a bit more to make it look like a G):
I'd play around with these ideas in Inkscape but I've got a DE test I need to take...
Edit edit: Also, the current logo looks much better than than the first "9" logo. But I like some of Prinz Eugn's variants a lot.
Also, I think favicon.ico needs to be updated...
