Standing next to your laptop to control the slides during a presentation is not cool. Nowadays everyone uses a presentation device or their laptop's remote controller, but a presentation device can be expensive, few laptops come with a remote controller, and for those that do, Linux compatibility may be an issue. The Amora project turns your Symbian mobile phone into a Linux presentation device using Bluetooth.
Amora comes with two applications: a server for your Linux machine and a client for your phone. Server installation is a straightforward configure-make operation detailed on the project's wiki.
