Wave Casual has released Nylon which they describe as a geometry-based synthesizer that makes designing sounds explorative and fun. Here's more details in their own words...
Geometric Oscillators
This new kind of oscillator lets you define the timbre via a circular path. The algorithm translates this path to sound, preserving aesthetic properties like sharpness, complexity and symmetry. Each oscillator comes with two shapes, that can be morphed into each other. This lets you easily create complex, interesting, moving timbres, all before the filter.

Motor driven synth has a sweet side..
Physical modelling instrument
Still tiny and DIY but impressive though
