My own Creach has a totally dead holo. One thing I was looking into was to get a digital photo frame or even a small LCD screen with a small movie clip on, thus once the holo was activated a short film clip would be shown.
This idea is still in the very early stages and power issues and all that goes with the workings are still giving me a headache. It might be a little out of my league but I am more than willing to have a bash at getting this working.
If this idea was ever made available , then I reckon you could do LOADS more with it than just replicate the original hologram on the screen, imagine movie clips , images etc - anything is possible IF you could get the LCD screen to come on at the correct times.
Maybe replicate the original holgram when it normally 'flashes' ( when getting the F I L M letter s) and run a short movie on the screen at other times ( when in 2 ball mode etc )
Just some thoughts.
