I went back and looked at some old photos, and the houses were the stormstruck house and the where's the fire house. Ok, so not those, what about the Piggy Bank Adventure or Test Lab?Busy morning...here, there and everywhere but finally ready to "play"
I'm going to really make everyone THINK BACK on this one; took this picture when Innoventions was full of demonstrations and activities.
This has nothing to do with a house or safety.
Keep thinking...not the Piggy Bank or Test Lab. Check some older pictures.
Could be! Part of "Disney history" here Jeff! 
Guess it's time for another little clue; "Innovations was born" after January, 1994 when this particular "exhibit" was closed.
lol just google and I know the answer but I will not say because I googled it
the first time I want to Disney world was for the 25th and that was in 1996
Pretty cool stuff, isn't it? 1996 oldest DD graduated from high school and she and her best friend went to DW on their first trip "without parents". Been going through older photos again getting Mom's Memory Video photos back in the right scrapbooks; such fun looking back at the CHANGES! Remember THIS?
Loved Veggie Veggie Fruit Fruit
Now you're on the right track! 
They closed CommuniCore in January, 1994 and reopened the revamped area as Innovations and I remember being disappointed when this was no longer there. Does knowing that lead you in any direction?
That's the direction you want to direct your thoughts...machines and/or computers. Another hint? These numbers weren't permanent...
Sure
. You said the numbers change, so I would assume it is a counter of some sort, but what it's counting, I am not sure. Maybe guests in the parks?
Not much help
Not much help
...
; it's counting people but not park guests.
Early volleyball game tonight so off shortly; see if this can get solved by the time I return later this evening
Almost there
