-:[The top of the panel has the 26 letters of the alphabet written, each followed by a hyphen and the letter "A" with a unique diacritical mark for each. "A - A" is the only letter in the top row, and the only one where that A on the right side doesn't have a diacritic. The next 25 is sorted in a 5 by 5 grid, with the first five letters after A in the first column, then the next 5 in the second column and so on:]

 It's named "Scream Cipher" (as a pun on {{w|stream cipher}}s, commonly used in computing) because the written form of a scream is often a long string of As, possibly with some other characters at the beginning or the end (and often an exclamation point for emphasis), such as "Yyaaaaaww!” or “Aaaaaah!" or "Aaaaaaagh!". The name may or may not be a reference to IBM's {{w|Scream_(cipher)|Scream cipher}} published in 2002.

+Say we want to encode "Scream" in the Scream Cipher. First we would need to split out word into the letters, so S, C, R, E, A, M. The first letter is S, so if we go to S in the table S is shown to become to Ã, C similarly becomes A̧, R becomes Ȃ, E corresponds to Á, A is the main letter so A is unchanged to A, and M becomes Ǎ. If we then write them again in order, we find SCREAM becomes ÃA̧ȂÁAǍ. To turn cipher text back into normal text, the process is repeated in reverse. To translate A̧ẢA̯A̰ÁȂ, we go to A̧ in the table and find A̧ becomes C. Ả similarly becomes I, A̯ becomes P, A̰ becomes H, Á becomes E, and Ȃ becomes R. If we write the letters in order, we see that A̧ẢA̯A̰ÁȂ becomes CIPHER.
