Thanks for the replies - that's all useful - particularly about the problem with multiplexing and the kit available. I enjoyed reading Terry's Electronika clock restoration pages.
I would be interested to know what components were used in the kit - would they use the tubes with the joined together spots like in the Electronika clock? Is the problem with multiplexing to do with requiring a pulsed current through the tubes? Would that shorten the life span? I was talking to someone who suggested that I used relays to provide the current and shift registers to control the illumination of the dots. The relays would make a noise which would make it more interesting, and possibly quite annoying depending on how much noise. Would it be possible to vary the illumination of the dots for greyscale values? If so would it be with pulsed width modulation (PWM), or controlling the voltage? >From what I understand it's technically quite tricky even with LEDs because our perception of brightness is logarithmic. However a crude 2-bit with 4 shades (including off) would improve the appearance of animations. Still haven't checked if they work or not!
