Einstein's SecretLogo Design Contest

Thanks so much for your submission! I really like the colors, and I like the design. Is there anything you can do to incorporate the "secret" part of the title in any way? I'm not sure what that would look like; it's just a thought...

Design update with emphasis on the word secret by using a stamp like typography (when agencies use it on secret or top secret folders) #50

I still really like the "secret" part of your design! I am wondering though, if there is also some way to emphasize the "learning" aspect? I'm not sure what it would look like, and you may think it will make it too busy, but I thought I'd ask.

Thanks!
