Here’s her setup:
The last few years my arms have largely shaped my work setup. I used to struggle with severe pains and cramps in my lower arms and couldn’t design unless I had my special equipment. Basically I assembled a device from a Manfrotto Table Top Tripod Kit 209, 492 Long, tripod adapter plate and an Apple Magic Trackpad and placed it in front of my 15 inch MacBook Pro. I then used the tip of my nose to draw and maneuver the mouse, while my arms were resting in front of me. Yes, it was pretty frustrating at times and yes, it looked ridiculous and yes, it took a long time to increase my precision and speed, but somehow I ended up becoming extremely efficient!
