I'm sure you are already aware of this site, however I wanted to suggest that a "references" compilation could be cool. All the bits from Simpsons, Family Guy, etc that feature Gremlins.

Also, I loved the Gremlins ride and it was so disheartening when I went one year and it had been closed to make way for a new piece of crap ride. I however, am referring to the Australian Movie World version. Which was similar but had some differences to the German one. Perhaps you could try and track down video of this one to show the difference? I know Alf wasn't there, people on the net say it was Beetlejuice but it was so long ago I can't be sure. There's some minor info here.
