...I am reexamining a book titled Adventures with Impossible Figures by Bruno Ernst, pen name of J.A.F. de Rijk. It's on the type of optical illusions in which perception of space changes, as with the well-known Candles and Profiles drawing, or the one of the Old Woman/ Young Woman portrait and others more complicated such as by M.C. Escher. I am wondering how similar effects might be created in short story form. Flash fiction, though a poem would be an impressive feat for the challenge. Thank you in advance for your creativity :)
