[Q] eassee3d for autostereoscopic screen by lemticular sheet topic

Eassee3d is an hw/sw solution to turn galaxy s3 screen into autostereoscopic 3d display.
Ok that's amazing... but hw is based on a 5x10 cm lenticular sheet which costs around 5$, but you must instead pay 50$ to buy the original hw!!
Does anybody know the specifications of the lenticular sheet suitable for s3 galaxy display? Or how to calculate the LPI density I need?
