I love iconic minimal lamps too. I never saw the Lampe de Bureau nor the Kismas Lamp 01, love them! You might like the Muuto Post.

I'll note that many of the glass blocks they use are available all over, for a few dollars. I bought a few Doric glass blocks, stuck some diffused LED strips below them, and printed a stand/enclosure, all for under $15. Good gift for friends.
