Four seasons was just an internal plugin Toby put together to test some graphical interface options and a user-definable oscillator, but he got a bit carried away by the interface and decided to release it as freeware.
Don't expect any super-hyper cool sounds out of this synth, this was only a test and you probably can't use it for serious work (at least this version), but feel free to play around with it a bit and discover the various options.
The new beta version of SickSynth now has a GUI and "is called the 'Bad Boys Beta', because you have to be a really bad and weird to enjoy this version of the synth".
