These tins are for different cuts of tuna. The packaging is cut to show the area of the fish in each can. It’s hard to tell in the photo but the lines are actually perforated so it’s functional too. The same packaging can be modified for different tins/different cuts of tuna.

The bolt rolls from right to left, and falls into an appropriate hole. I find this an example of a really simple yet clever engineering.

Recently, I took a flight with Turkish Airlines and had a layover of about 11 hours at Istanbul airport. The airline has this service of free tours of the city if the connecting time is over 6 hours. It is called “Touristanbul”. Not sure if the design is great, but the name is. It is an arrangement of the words “Tour” “Tourist” “Istanbul” and “IST” (the IATA code for the airport).

The Chapel of Mary's Mantle is a chapel dedicated to Our Lady of the Mantle on Freising Cathedral Hill.

The chapel is located directly north of the Freising Diocesan Museum and was designed by Kiki Smith. The architects Brückner & Brückner Architekten were responsible for the renovation of the museum, which was completed in 2022.

The entire structure was built from stacked plain tiles from the parish church of St. Georg in Ruhpolding and was left unrendered. The tiles were replaced when the roof was renovated. The base area of the chapel is 4 × 4 m, with a height of 8 m. Both the roof with the cross gable and the entrance are built as a corbel arch or cantilever vault. A gilded dove sits on the north-western gable, facing west.
