Update extended description

A collection of original digital works, made in Procreate on an iPad Pro/Apple Pencil, of the theme: impossible objects and structures, generally in triangular formation; more specifically, variations of the Penrose Triangle/Penrose Tribar first created by Swedish artist Oscar Reutersavärd in 1934. The New World Encyclopedia describes it as such: “At first glance, the Penrose triangle appears to be a two dimensional depiction of a three dimensional triangle built from square beams. However, the properties of this two dimensional drawing cannot be realized by any three dimensional object. Hence, the Penrose triangle is an "impossible object." Lionel Penrose, a psychiatrist, and his son Sir Roger Penrose, a Nobel Prize-winning mathematician, popularized it some years later in the 50’s. They described it as “impossibility in its purest form.”
