the log is very simple. I just use the Copyright logo, rotated on a 90 d. angle and it looks like a smile face making fun of the original idea of Copyright ©.
I also use Helvetica Rounded LT Std because everyone uses Helvetica and is very comercial, but the round one is a fun version of it.
PS: Sorry I can't write more in English.
I'll in Spanish if you want mi to.
