My students came up with a hairband tht would record everything tht your brain thinks when u press the start button…save it all in a memory card and later on u can access it…They thought it would be important for writers..they can record their thoughts before they forget it
I want to invent something to make me ‘invisible’.
I think Sony did have that kind of ‘lense’ accidentally on a digicam, can’t remember that model. BTW in childhood I remember seeing a ‘catalog’ with different gadgets and one of the spectacle was said to be what you are asking for, never tried to get one though.
I thought for millions of inventions .. when i sat down to actually invent them i realized that it has already been invented by some jerk who is known as "scientist" to the real world!
I like to combine LP and Hareem’s idea and use that hairband as waistband of the glowing underwear. One can only imagine what the memory card would record
