Blender 3.1 alpha: Erindale Projection
Bizar mapping of an image onto the monkey. I took a cylinder (with UVs), made a cut at the loop where blender cuts the UVs (the one pointing in +y) and deleted two thirds of the tube, left and right, since they contained no head pixels. The remaining third i draped around the head in order for the geometry node modifier to be able to work propperly.
EDIT: The video might partly be a bit misleading. For clarity: the projection works even without a material on the image mesh. It's the comparison of the normal angles of both meshes that makes this happen.
