Purva's birthday gift

this is a idea came to Smruti and myself when we stumbled on a site with something similar. we just needed a reason to try it out. the first occasion that followed was purva's birthday.
we wanted to make this out of paper but i wasn't possible. cause i can imagine the illusion that will be created when we flip the pages. maybe soon(i'll upload a better picture of the final out put soon)
