Just look at the structure of this alkaloid!

Sometimes you just have to step back and marvel at the structures that are found in nature.  Check out zamamiphidin A, a new manzamine alkaloid isolated from an Okinawan sponge by J. Kobayashi and co-workers (Organic Letters).  Heptacyclic.  Quaternary ammonium.  Massively bridged.  Well done, sponges!
