Find constellations in an ordinary ceiling

I can see these harmless ceiling or wall details: [DETAILS]. Invent three fictional constellations using only those described points. For each give a shape guide, a two-sentence myth, and one alternate interpretation from another invented observer. Add a quiet two-minute noticing exercise and a plain disclaimer that these are not astronomical constellations. Do not require photographing a private room or looking at a light source. Check that the point references are traceable to my description and that no invented star is presented as visible fact.
