Warehouse 13

This summer I watched the current season of the SyFy original series "Warehouse 13."  I must admit that I really like the premise as guide to magic items for a fantasy campaign.  Each "artifact" in the series is a different magic item, each one unlike any others.   The magic items aren't created on purpose, but become magical spontaneous, linked to their famous owners.   So, one artifact might be Gallileo's telescope, another might be the binoculars from the Enola Gay.   Each one has a unique power, but also some "downside".
