cores look inside to see the rest of the patterns on the cores i put this up to celebrate me finishing portal 1 :D i know i probably wouldn't have wheatley here or the other cores i didnt include the demon core that goes like GDOFKHSLKDGFHRSHDFGHRH at you in portal 1
every single core from portal and portal 2 this is how i think each core looks try and guess them all in the description (some are obvious) i did not draw these just colored
