I made something similar with a knock off google cardboard plastic vr headset, some wide range led's, tracing paper to protect the eyes and spread the light and an arduino with a potentiometer hooked up to it. Quite cumbersome at the moment as it's spread over 3 pcb's(one each for the led's and resistors and one for the pot) but it's absolutely brilliant at higher blinking speeds. Very trippy but i fear there may be some nausea involved. I haven't had the time to indulge fully yet lol. Regardless, thanks for the inspiration. If I make another one I will take pics of it step by step and post it!
