Shane Wighton of Stuff Made Here built an automated washing machine for his muddy dog. Shower nozzles move over a platform and spray from below. But his dog Eva was frightened by the machine, so another dog, Brie, took part in testing.

This camera only takes a photograph when there is a dog in the frame. The presence of a dog is built into the rules for whether the camera can take a picture at all.

It is a creation by Matty Benedetto, who shares deliberately unnecessary inventions on his own site, Unnecessary Inventions.

The feature film Garagara, Akuta is in preparation. It follows a father who spent his time making impractical inventions and a daughter who left home partly because she disliked his projects. After her father develops young-onset dementia, she begins rebuilding one of his unfinished inventions with help from people around her. Filming is planned for December 2026, with completion expected in spring 2027. The production is raising funds through crowdfunding.

The film is written and directed by Asuka Hachimaru, with Shigehiro Yamaguchi playing the father. Daiju Ishikawa, founder and organizer of Hebocon, is involved in supervising the film's inventions and building large-scale props. Even the film's title lettering was created using cardboard and a toilet-paper tube.

The Tragic Mouse is an iPhone case that also works as a functional computer mouse.

It was created by Matty Benedetto of Unnecessary Inventions, a maker who builds deliberately unnecessary products. The creator's official page lists the device as operational.
