I picked up a new (well, used but in great shape) overhead projector recently. This one is "portable" so it comes in a little suitcase and weighs like 6kg. Replacement bulbs are about 4€.

I like that it's technically simple and repairable and other than the bulbs, not much is likely to break soon. There is no dull prescriptive software suggesting that I make slides in any particular format. I can even do fun stuff like put two slides on top of each other or draw or write directly on them. I can make them digitally, analog or in whatever mix I like.

It's a cool format.

Any other #overhead heads out there in the Fediverse?
