f.lux
Clicking around the interwebs I came across f.lux. This is an app which tweaks your display at night to make colours warmer and reduce the amount of blue light emitted by your screen. Blue light (a la daylight) keeps you more awake and alert, and the idea is that reducing the amount of blue light you see reduces the potential disruption to your sleep patterns. Let's just say that the oops-I-should've-been-in-bed-3-hours-ago habit is one I need to break, so I'm giving it a go.
