Standing Desk for designing, illustrating, drawing etc

5 years ago from , Designer at Tigerspike

I am a designer for a technology/software company and I am looking for a standing desk solution.

My current tools are:

RMBP + Thunderbolt Display 27"

A3 note pad

The majority of my work is on the computer using mouse/keyboard but I am frequently sketching and drawing.

Has anyone come across a solution that allows for swapping between sketching/typing, different heights/platforms for the keyboard etc...?
