Ask HN: Standing desk hacks?

I work in a cubicle farm (in my case, 6'x8', drawers/shelves on one side, formica desk surface wrapped around 2 sides, pre-drilled hole in the desk for workstation cables.) The company will make some inexpensive accommodations regarding ergonomic chairs, and keyboard trays, but I'm interested in working while standing.

I've jury-rigged a set-up, but I'd like to hear of any good hacks or commercial equipment that integrates with/attaches to an existing cube desk to enable comfortable, healthy stand-up work.

Thanks!
