I just ran across this pre-print article http://arxiv.org/abs/1206.4058 on a star system that apparently consists of a pair of eclipsing binaries. The two close binaries have a period ratio close to 3:2 so although the light curve is pretty bizarre it's repeating. The system, CzeV343 = GSC 02405-01886, is in Auriga and is reasonably bright at V=13.5. It's not clear yet whether this is really a quadruple system - it's possible that two unrelated binary systems just happen to lie in the same direction. Long-term monitoring of the eclipses should eventually show light-time effects as the two binaries revolve around each other if the truly are related.

Dear Shawn,
Thank you for calling our attention to this interesting system! As I can see this system is not in the VSX database yet. In the article I haven't seen any coordinates or identification for this star, but this site http://var2.astro.cz/EN/obslog.php?obs_id=1&star=CzeV343%20Aur
gives the following position for CzeV343: 5 48 24 +30 57 3.6, +/- 1 arcmin (J2000).
