Sorry for the delay and thanks for your great contribution, we appreciate your efforts but the "I" is too hidden maybe the "h" suits better for an illusion like that... And the double cube is more confusiong than illuding (IMHO), try something simpler, thank you
P.S.: the concept is that you have to clearly see in the logo 2 different pictures, both clear and simple, but without the ability to choose witch is the main one.
