What are the really unusual or weird computers?

Parallel systems in any form are probably worth a mention, too, even if the users' perspective is usually just bashing out some code to run on them via a more conventional system (Sun, PC, whatever). In terms of cosmetic design, I'd have to give credit to systems which were completely integral to the desk at which the user sat (HP 250, BCL SUSIE etc.) In more recent times, did Sun ever manage to get a CPU running which directly executed JAVA bytecode? (by recent I mean ten or so years ago now probably... I remember futzing around with one of their Javastations back then, but I believe they were just a conventional CPU and the true "Java chip" was still in the design phase - I'm not sure if it ever left) The various set-top boxes that I've seen have been pretty darn quirky too, at least in terms of HCI (and as a demonstration in cost-cutting!). I'm yet to see a good one. At least some of the Acorn models would actually boot a full OS though given a bit of hacking (I seem to recall being able to kludge a Zip drive onto them for storage)
