M8AX - Prime Numbers In Matrix 640x480

Every 18.5 seconds in the video there is a transition. The first 18 seconds only the prime pixels are painted in a 640x480 matrix, which end in 1 starting from pixel number 1 to pixel 340000000 more or less, obviously a 640x480 matrix only has 307200 pixels, but in the video there are many frames of 640x480 and when one ends, it continues with the next one... and it continues counting primes... with the primes that end in 3 it does the same and with those that end in 7 and 9 as well. about 18.2 seconds for each completion. and in the end all together with different colors. Is there any pattern? don't tell me the black columns because that's normal... if it's a matrix at the end, those that end in 3 in 7 will always be in the same positions... If someone sees something, say so because it's interesting... ... https://www.youtube.com/watch?v=lDK3rJh1O_o
