Since this comes up regularly, though only from very few people, and we as the ones never seeing it from the audience side obviously have a different point of view, quite literally, honest question:
How much does seing the stuff holding everything together ("the machinerie") distracts you from the story or even spoils the experience for you?
We have lots of things which are required to make everything work, and we try to put everything in black - both, because black can be mentally ignored more easily, doesn't shine and distract by itself, and also as a clear cue to the audience what is intended to be part of the play and what is "the stuff behind the curtain". Those things include the metal hooks for the backdrop paintings, gloves and balaclavas for our puppetteers, lighting fixtures, rods on puppets and props (=all the non-puppet, non-decoration items we handle).
We are also aware of the perspective issue, which became even more important since we don't play anymore directly at the playrail only, but also behind each other - people in the front row have a steeper viewing angle than those in the last rows, whereas the cameras are both further away and placed higher, necessarily to not be obstructed by the audience. Our effective maximum puppet height is literally "one arms length" - thus we can choose between showing as much puppet as possible and a few heads, or no heads but also less of the puppet, too. We did actually discuss this and decided that it's worth asking our audience to ignore the heads as they are ignoring all the other black things already, than to display talking puppet heads only, w/o the body interaction and arm movements. After all, it IS a live puppet play and not an animatronic TV production.
Thus, I'd be interesting to hear whether those heads really bothered you that much, and whether you can explain why it makes such a difference to you?
