WARNING: Spoilers for the Doctor Who episode “Day of the Moon” ahead.
I really liked the nanorecorders from the episode. I started wondering how cosplayers and such might emulate the special effect of the nanorecorder in a live setting, and thought of the UV-reactive invisible ink used in things like hand-stamps at concert venues and nightclubs. This is a quick-and-dirty sketch of how such an idea might be put to work.
If you manage to make this effect work, please let me know!
