From 15th Century painting to NFTs: “Meta.Space: Spatial Visions” opens at Francisco Carolinum in Linz, Austria, gathering over 30 artists that examine “social, real, and imaginary space.” Next to the virtual worlds of late luminary Herbert W. Franke, for example, towers the site-specific ‘crypto sculpture’ by Alexander Grasser and Alexandra Parger. Open Architectures (image) is a wooden model of one of 50 community structures built collaboratively via interactive NFT.
