I saw this on ibles from JustAddSharks' DIY Heng Lamp and thought it looked really cool and just decided to go ahead and make one myself. The main difference is that I elected to use 3D printing instead of laser cutting to make the lamp body. It might not be as aesthetically pleasing as JustAddSharks' (or the original kickstarted heng lamps) but it was easier with the tools I had. It is a cool looking lamp and I like the magnetic actuation!
The whole project can easily be done in a day if you have all the parts and access to a 3D printer and soldering iron.
I had all the parts already so I don't have any links to share. That being said there aren't many components needed and they should all be cheap.
