Black, hairy jumping spider with 4 eyes and green fangs:
UPDATE: On June 26, 2007, Eric Eaton at bugguide.net identified this spider which I described as being 1/4 inch diameter:
Actually, 1/4 inch is pretty 'large' for a jumping spider. Most of the diversity in Salticidae seems to be in a much smaller size range. This is a male of some kind of Phidippus. They vary greatly in coloration and pattern among individuals, so I can't put a species name on this one. Not a dangerous species, and good to have it on pest control patrol:-)"
