when i was at work this guy had a fidgety doo thing but it lit up and he spun it really hard with an air compressor (we work in a automotive repair shop) and this was of course in the dark after hours when we were hanging out and yeah he starts spinning it just unbelievably fast, and it's like strobing rapidly with all these colors (i don't know where he got this thing haven't seen one like it since). Needless to say i have severe epilepsy (me and this guy don't know each other well enough for him to know that) and i went into a really awful seizure where i somehow rolled on the ground into the pits where we do oil changes (i'm sure you know what i'm talking about, there's a area underneath where the cars pull in so you can do oil changes standing up. Anyhow i'm sitting here now doing this precisely because i broke my leg pretty bad when i fell into that pit. These things seriously have to be stopped, they're a danger to society.
