a blissful accident/what did i do and how did it happen?

[MishkaKatyusha]

i was busy texturing a house object im working on.

then for the specular map i used a background-less screenshot rendered in sculptris

then something very unexpected and amazing happened that i cant explain

 

the entire surface of my hosue object became alive with the bright parts of the image in question,little symbols in repetition that would light up only when i get close to the surface

 

as i mvoed around the object it made it seem alive,with beautiful 3d symbols coming on and off

id like to know how this happened so i can repeat it in the future
