“Silkhenges” are silk spires surrounded by an intricate silken fence structure. We know they are made by a species of spider; scientists aren’t sure yet if the spider is a described species or not. This entire structure is only about 8mm (.3") in diameter, from Amazonian Peru.
They have less than 5000 years to go before they create the integrated circuit.
I, for one, welcome our arachnid overlords.
