Scintillating Neon Illusion
K Shiina, K Shinohara, T Fujii, M Takashima
When crossing portions of black line grid are replaced with red crosses, the reddish color spread is observed between red lines: the neon color effect. When red crosses are rotated some degrees to disconnect with the black lines, the neon color disappears. We report here two new observations relating to the neon color effect but in motion. (1) When red crosses are rotated in constant velocity, neon color will be observed only when red and black lines are connected but with slow velocity, suggesting that the neon color effect needs some processing time to develop the phenomenon. (2) In the second condition, the black crosses are not removed from the grid, and red crosses are rotated over them. When they are superimposed, red lines overwrite black lines. On observing this motion an amazing red flashing can be seen at the moment of superimposition. We named this phenomenon as Scintillating Neon Illusion. The flashing neon will be observed not only in rotation but also in transposition or in flickering replacement of red and black crosses. One of the parameters of the strength of the scintillating neon illusion is the total length of the superimposed lines. The underlying mechanism will be discussed.
