My desk at Plangrid's office.
I'm a big believer is color and light. Just like the broken windows theory a chirpy workspace has a positive effect on my work. A lovely bright Sol Le Witt work as a desktop and a warm table light that always stays on help with this. The poster in the corner is by one of my favorite designers, Always With Honor.
Wacom's rock. It's really fast to go from typing to Photoshopping with a pen instead of a mouse. The new Intuous can also act as multi-touch targets which is handy for debugging iOS stuff.
Finally, the chair is temporary. We've got parts for standing desks coming soon.
