My eyes were feeling a bit tired today so I installed the Stylish extension and an excellent style called "NightShift - eye care" that changes all colours and even dims images. Another reason to stick with Firefox.

I also installed this Zenburn Windows XP Theme (zip) based on one by Jason McBrayer. Zenburn is a low contrast colour scheme originally for Vim.

Now it's like my eyes are resting in a pool of cooling grey.
