This is my DIY version of the Ripples, the first version of Emelie Gilet's filter. It is based on the 2164 chip, a QUAD (I said dual in the video) Voltage Controlled Amplifier. Its an easy build of a really nice "liquid" filter according to MI documentation. And as you can hear there are a few times where it does sound very liquidy ;)
This video comes a little late as both the files, and the product in the store and the build video is already done. Sometimes time runs away from you ;)

You can find this as a kit (without the 2164) or pcb+panel set in my Tindie store here:
tindie.com/products/Sourcery/riddles-a-throughhole-version-of-the-mi-ripples

Or you can download the gerbers and order your own here:
github.com/SourceryOne/Riddles

You can find the Alfa version of the chip AS2164 here: https://www.ericasynths.lv/shop/ics/quad-voltage-controlled-amplifier/
Make sure to buy the PDIP version, and also maybe buy some extra chips for a Veils version that I hope is coming, and some ES Polivoks VCAs and VCFs?
