that's exactly (in ascii, that is) the idea behind randomart, eg

    The key fingerprint is:
    SHA256:s6N0OwlTDKjDez98kZRwUGZbTYaQUArv+EYC6sigFwA ben@eshwil
    The key's randomart image is:
    +---[RSA 2048]----+
    |E   ..o=*o.+o    |
    |.   .oo+oo...    |
    |....  o=..       |
    | o+. o  =        |
    |o .oo ooS.       |
    |* ...+o oo       |
    |oo.. o+o+o       |
    | .   o+o+o       |
    |      .o..       |
    +----[SHA256]-----+
