List of Publicly Accessible MySQL Databases?

[Andrew J. Leer]

Is there a listing of public MySQL Databases anywhere?

Just if someone would be new to databases (not me...other people at my
office) and they would want to get a look at an existing working
database to learn SQL on?

I've found one such database:

Genome Bioinformatics
    db.host=genome-mysql.cse.ucsc.edu
    db.user=genomep
    db.password=password

But I really don't think the people I'm trying to teach here know much
about Genome Bioinformatics (and ah consequently I don't know anything
about that either...)

Thank  you,
