Viewers of the pattern or of photos of the pattern observe the protrusions as block letters in a language they are familiar with, but this is merely a visual illusion. No subject has reported any subsequent change in the appearance of the letters. On the bottom of the object, there are four (4) 1 mm x 5 mm crevices, each coated in a copper-colored substance. No new effect has been observed through the manipulation of or application of electricity directly to the crevices.
