Hi @Grant [Tobii], many thanks for your information! In the meantime I have bought a couple of styrofoam heads and some sets of fake eyes, but I can’t seem to find a setup that works well. The eyes are seen sometimes, but not all of the time, I would even say mostly not. It also seems that they can be seen when they move, but not when the styrofoam head is just standing there. There is a huge difference between my own eyes and the fake eyes on the styrofoam head. What head/eyes combination do you propose, and are there other caracteristics which are important? Maybe you can sell me a styrofoam head and fake eyes set?
Thanks again,
Pete
