After creating a model for the Torben Holmback Tape Block (Thing #7018881), I went down a bit of a Holmback rabbit hole. He hasn't left too much of a digital history. I found a pencil holder that seems to go with the tape block, but not much else. Except this origami style lamp which I think is very cool. I found a couple of examples that had been sold on auction sites. Nothing currently available or in production. One of the auctions referred to it as model A4 by Torben Holmback for B. J. Metal. Nothing at all (except the auction listing) when I search B. J. Metal.
