The rarest, and one of the best Amiga models built, along with some Amiga image processing, can be seen in Italian thriller "Fatal Frames" ("Fotogrammi Mortali", 1996).

In this late giallo one of the characters reviews some video footage using an actual Amiga 3000T. It's not the most exciting movie ever, but this might be the only time this rare Amiga model has been put on film.

Writing a demo is a lot of fun, because there are basically no limitations. You just use what you have, and there's no fixed goal. You can make it as short or as long as you like, and when something doesn't work, you either change it, or just drop it. 

While all along the way, of course, you run into a lot of issues. A proper demo generates graphics and sound, and has some sort of timing. That's a little less work than a game, which additionally needs user interaction (input) and "rules of engagement", but it's still quite a lot to handle. 

Walkman, arcade, Live Aid: Pop band "Men Without Hats" of "Safety Dance" fame released an ode to the `80s a couple of months ago, that features an Amiga 500.

Ok, admittedly, the Amiga really plays only a minor role here. But it's always fun to see one out there in the wild, and in this particular context, it's evidence how much of a cultural icon an Amiga computer is. Who would've thought that 40 years after release it shows up in a YouTube video that got 1.5 million views in its first nine months?

This looks oddly familiar. But it still doesn't boot AmigaOS 3.2. Sigh. ;-)
