I found this Camera Restricta project recently and then the further work of the designer that created it:
Have a look through his portfolio and realise that it’s entirely ‘just student work’ and that he only graduated from HfG Schwäbisch Gmünd last year. Also, that the video above isn’t just a concept, but something he actually built as as working prototype. Bonkers. The ability of some graduates these days is just remarkable.
