Virtual Fish Doorbell

This livestream of a Dutch canal lock has a virtual doorbell viewers can ring to snap a picture and let the operator know fish are waiting to be let through. It doesn’t really open on demand, but the idea is very charming. If you scroll down you can see all the fish that have been recently spotted. I found it in the Deepculture newsletter, just back from my first trip to Amsterdam where I rented a boat and navigated the canals. It felt synchronistic, like a souvenir from my trip. — CD
