Thought i would start a new thread for these, i am sure there will be many as folks get smartphones.
Two for Android from me, Remotedroid is a wireless (as in IP not Bluetooth) keyboard and mouse for a PC or laptop using your handset. Requires download of a java app to your machine which can be run at startup. Works fine here, typing this on the TV and media center.
FXCamera uses the phone camera and applies fun effects like fisheye live as the picture is taken. Lots of photo packages do this but its nice to be able to compose and take the picture with the effect on, like an SLR does. By no means a must have application, but great fun anyway. Three pics of my dirty dinner plate with Warhol, fisheye and symmetric distortions applied attached.
