The more people look, the more they'll see. I did produce Seriously in a way that gives it a confusing three dimensional appearance. Some people see a flat image, others notice the depth. It's different for everyone.
I can see how my stuff can kick start the imagination. That's why I don't say much about them. Everyone has a unique experience. Nobody is right, nobody is wrong when it comes to what they see.
Apparently lots of people enjoy it. As do I.
