Nice. Actually I was helping my kid with his geometry homework before this and it involved rhombi.
I think that means I messed up and didn’t clear properly before working on the construct, and/or I need to put more work into the construct to link it and not the echoes of maths in my space.
Trying again - same construct: here
Another think that happens is that people pick up nearby physical objects instead, possibly becuase they are more cemented in the astral having sat there a while - so if you see a dark red box, look the the right of that. Oh but also watch for spatial flipping and size reversals in the astral.
I’ve seen photos by astral mail, then the real photo, and found I saw them in mirror image.
