This video, via seho chang, demos the Dotcom-style 5U version of the Synthesis Technology E350 Morphing Terrarium.

The E350 Morphing Terrarium is a wavetable VCO with two independent waveform outputs, with voltage-controlled morphing between waveshapes. The module features 192 basic waveforms, but also calculates 128 “in-between” waveforms, resulting in over 24,000 individual timbres.

The Dotcom-style 5U version is from Low-Gain Electronics.
