nitoTV is burning the midnight oil and has tweeted a new repository from which you can grab the first GUI-based AppleTV2 app (technically a Lowtide plugin), which currently has weather and RSS functionality.
To use it, do the following:
1) SSH into your Apple TV2, the default password is “alpine”
2) Type “passwd” and enter a new password (if you haven’t already)
3) Type: echo “deb http://apt.awkwardtv.org ./” > /etc/apt/sources.list.d/awkwardtv.list
4) Type: apt-get update
5) Type: apt-get install com.nito.nitoTV
6) Type: killall Lowtide
