Predicting an incoming 'Pyra-chan'.
More random:
I'm still partial to the first design I posted that was derived from the Pandora icon though.
To be honest, when I first saw this, I thought it was a rat or mouse (for 2 seconds or so). That's probably because of the tail and overall shape, and because I tend to look at things left-to-right. It is not clear what the cube is supposed to represent. The text logo only works in lowercase, in uppercase it looks like PYRA dRAGONBOX. I would put the "DragonBox" first and the device name second. The infinity symbol on its own is not sufficiently unique, and people will probably wonder what this "8" is supposed to mean (does it run Windows 8?
).
I don't mean to be negative, it's just my honest and hopefully constructive feedback. I like the general idea, and it's a good start. Keep going!
(I like ambigrams more though)
