I found out that you can make a makeshift projector with just a magnifying glass and a smartphone(brightness on full) in a completely dark room. Put the two implements roughly a foot apart and a 3ish meters away from the wall. Good for projecting trippy visualizer music videos onto whatever. It's just crisp enough to use for tracing things as well, such as sewing patterns so you don't have to print them out.
@email@example.com are you familiar with Valentina? I recently discovered it. It's a free open source clothes pattern-making program with tools to customize patterns to personal measurements https://valentinaproject.bitbucket.io/ I haven't used it, but the codebase is being actively updated and its features look very rich
there are so many that are locked or deleted now. the only version of unknown vision available is the version truncated for the anime ending it was on, doesn't even have the awesome second chorus but worth the listen anyway imo https://www.youtube.com/watch?v=GLixG6LMksg
