As an alternative, you might want to consider LifeHash, which includes a visual indicator as well as a readable fingerprint value.

LifeHash is an open source visual hashing algorithm that we use for all our projects. Lifehash has a number of desirable qualities, including high complexity, good aesthetics, a printer-friendly (CMYK) color gamut and robustness when transformed to grayscale.
