Since I love viewing documents on a horizontal screen (especially now with my s10e) I decided to write an application that could rotate the OSX Desktop. At the moment it is working rather well so I wanted to share a first version here with you.
The app is called DisplayTwister and uses Quartz to 'redisplay' the destop image in different portrait and landscape modes. Also, when you apply a taller monitor resolution with SwitchResX you can get a fullscreen portrait mode and use DisplayTwister to scroll over the entire desktop image.
There are plenty of drawbacks with DisplayTwister, most notably the performance and the font aliasing, but it is very convenient to read long texts with the netbook turned over. (Tilt the screen Left and you can use your thumb to use the PgUp/PgDn keys on the Lenovo s10e)
And I can imagine that DisplayTwister can help installing programs (in combination with SwitchResX) and give access to dialogs that are bigger than the screen.
Give it a try, doubleclick the app and press the cmd-arrow keycombinations to tilt the screen. When you want to quit or change the orientation just cmd-tab back to DisplayTwister and press cmd-q or another cmd-arrow keycombination.
I love to hear your experiences.http://captv.nl/rob/DisplayTwister.zip
Known issues; the 'real' mousecursor will popup at times and the simulated mousecursor will not change it's shape.
Oh, and i stole the icon. It will be replaced in a future version.
