Here application and game from here.... Enjoy it!

For those of you not familiar with BackTrack, it’s a GNU/Linux distribution that is used for security testing providing users with a wide range of tools from port scanners to password crackers.

The OS is fully Ubuntu-based so it is possible to run it like a desktop, including running Firefox and other Linux applications. Other features of BackTrack 5 include being able to do advanced network scans right from your Android device via WiFi, no laptop required.

From XDA- Forum:
BackTrack 5 installation guides are making their way around this forum. I've tried to synthesize it all, but I've also added my own touches to help with usability and features, along with a workaround for the "ioctl LOOP_SET_FD failed" error message some people have been getting.

In theory this build is nearly universal, so if you have an Android device it should work. I've put it all in one zip file that you can download directly from my website, no hassles or wait timers.

If you are interested have a look, feel free to re-post. Credit goes to the BackTrack team and xda member anantshri (he's got skills, give him props guys), who built the base image file.
