I haven't yet completed a real telivisor, but I've done a lot a playing around with the software others have mentioned. as pointed out the problem faces is that the club standard is portrait, favouring headshots, rather than the usual landscape format we are used too.
however, by allowing the led/diffuser/lens assembly to be rotated through 90 degrees around the disc to the top (like in IIRC the german mechanical system) 32 line standard landscape pictures can be obtained. This obviously adds to the mechanical complexity of the viewer, but I'm sure makes it much more useful for actually looking at pictures
I seem to remember a televisor shown at the NBTVA convention last year that was capable of viewing portrait baird signals, and landscape german signals by the rotated light source and mask design.
I have encoded an old bugs bunny film with the avi2wav program in a landscape aspect, here's a very short snippet of the resulting wav file.
I don't know how good it looks on a real machine, but on the software viewer it is very watchable.
