Greetingzzz ~ ~~

Passing by to sprinkle some three-hour cyber rituals of one open air night shift at KALT Krimmeri Alternative, Strasbourg.

After very moving experience at OutsideininsideoutinsideoutoutsideiN in Saxon Switzerland's nature, I drifted back to my hometown. The results of covid test stated "negative" so I hop onto another adventura to a small city of Strasbourg in northeastern France where the number of covid cases was below the number of all my fingers. Spent first few days getting familiar with the unfamiliar, strolling around by feet or two wheels alone or in a company of lovely people of the KALT collective.


Served this one for the unknown and fully masked swaying organism in the newly explored zone. To make the dystopian setting a bit more puffy, spicy ingredients home~cooked by the fellows from Prague, Montreal, Taiwan were drizzled and stir~fried into cyber~tentaclish noodles.
To be consumed flaming hot during lock-down-knock-downs. Also single pajama party friendly
