There used to be a fun store called Think Geek that would announce a bunch of new products on April 1st. Some were clearly impossible, some they were actually planning to launch (usually more mundane stuff like shirts), some were things that were more “this is a joke but if enough people like it/express interest we’ll see if we can actually manufacture it/license the IP.” I liked the site and realized only a few months ago that I hadn’t seen anything from them in a long time. They were independent, then bought by the parent company of Slashdot but kept operating largely as normal, then were eventually sold to Hot Topic and I think that’s when it kind of went away. Looks like their site now redirects to GameStop.
