Vladimir Gvozdeff (Gvozdev) is an artist from (if I’m not mistaken)
Slovenia Russia [I was mistaken, see this post’s comments], who works in both two and three dimensional media, often combining them in the same work.
On his website, I found two series of particular interest. One is of mechanisms — clockwork animals drawn out as plans in various stages of finish. These are sometimes presented in elaborate frames, or even more elaborate assemblages, that combine the drawings with various mechanical and pseudo-mechanical objects, like keys, buttons, gears, wheels, calipers, slide-rules and various measuring instruments. The effect is one of viewing an alternate reality museum exhibit presenting the history of the development of these now familiar objects.
The other series I particularly enjoyed, while not a combination of two and three dimensional art, does deal with dimensionality — but in a different way. These are paintings in which open spaces within cityscapes, like harbors or plazas, take on the form or animals or other objects.
