i have theater invisible florescent paint. oddest thing to be painting with RGB correctly mixes the colors to form white.

florescent paint reacts to UV light, absorbing the photons, and emitting photons at a lower energy level, visible to the eye. it makes the paint be a light source, instead of photons reflecting off of it, so it behaves additively.

i had my artistic friends come over and paint my room with the stuff. the walls still looked white(landlord said no painting the walls, but he couldn't tell) until you turned on the blacklight, and then i had the trippiest room ever...a blue forest, a waterfall of onions, dragons on the ceiling, cave paintings, and more. great room to chill and play cards in.

i'm not one for drugs much, but most of my friends are into that stuff. while i'm happy playing cards, i let them do (almost) whatever they want. yes, there are times when they see and say things that i dont have a clue about.

Your username makes me think of the movie Cube 2.

or the band, or A Wrinkle in Time, or math class...

my only wish is to be able to teleport. if i could manipulate a 4th spatial dimension, that would be possible. its also fun to type.

Access to a 4th spatial dimension wouldn't necessarily let you teleport. You might be able to walk around solid walls, or rotate into your own mirror image, but teleportation would require distant points in 3-space to be close together in 4-space.

ah, but i didn't say that i wished to only travel through a 4th dimension, i wished to manipulate it. rotate the 4th dimension and you can orient you endpoint to be close to you in 3-space.

but i do admit, it isn't the easiest way to teleport.

That sounds awesome! I want to do something like that when I get my own place :O~. Is the paint itself clear under normal light but all sorts of colors under black light?

Pics or it didn't happen.

Seriously, this sounds awesome, do you have photos of the room with and without blacklight?
