- A user shared a direct link to a PDF on implementing Lloyd’s Algorithm (k-means) on GPUs: “Lloyd’s Algorithm on GPU.pdf” (http://ldc.usb.ve/~vtheok/cursos/ci6323/pdf/lecturas/Lloyd’s%20Algorithm%20on%20GPU.pdf).  
- Paperbot successfully retrieved and mirrored a JSTOR article for user drewbug: http://diyhpl.us/~bryan/papers2/paperbot/2db97ab57df4b5e9fa16e7154b98435.pdf (original DOI 10.2307/3881284).  
- Discussion critiqued a custom split keyboard project (http://yager.io/keyboard/keyboard.html) for using flat PCBs instead of a fully reconfigurable 3-D key layout.  
- Proposed an alternative “jigsaw-puzzle” plastic jig concept that could expand/contract to hold individual mechanical keys in arbitrary 3-D positions, enabling ergonomic, user-specific keyboard geometries.  
- Referenced an earlier art piece: a welded small-diameter steel sculpture that arranged keyboard keys organically in 3-D space, illustrating precedents for non-planar input devices.
