Pe Lang has a temporary exhibition in Paris (in https://www.deniserene.fr/) until ~first week of July: https://bibliogram.art/p/Cdf2MDjseRm

Pe Lang makes artifacts that, for me, show some nonobvious or obvious-but-often-overlooked physical property. https://www.pelang.ch/works.html has some examples (but even not the ones I liked most when I saw his exhibition in, sadly defunct, museum of digital art in Zürich).
