For each prime p, I'll describe a construction (modelled on an old one of Priddy) of an E-infinity ring spectrum R that seems tantalisingly close to BP. Indeed, if BP admits an E-infinity structure then these E-infinity ring spectra are weakly equivalent. The techniques used may be of wider interest and along the way I'll give some very classical looking formulae in a new guise.
