WifiEye is a tool to visually display available wireless networks. It is based on wifi analyzer which is available for android phones.
WifiEye is written in python and uses the Qt library and python-wifi library. This makes it very portable and it is easy to port it to other Linux-based platforms.
WifiEye is available from the Maemo Downloads page.
Source code is available using standard debian tools (apt-get source) for maemo. If you have trouble downloading WifiEye’s source code, contact me.
