This oneliner was stolen from a Digg comment about the Java Project Looking Glass 1.0 announcement:
mkdir /tmp/project_looking_glass && cd /tmp/project_looking_glass && wget https://lg3d-core.dev.java.net/files/documents/1834/46211/lg3d-core_1.0.0_i686.deb https://lg3d-core.dev.java.net/files/documents/1834/46216/lg3d_jdk1.6.0_i686.deb https://lg3d-core.dev.java.net/files/documents/1834/46215/lg3d_java3d_1.5.0_i686.deb && sudo dpkg -i *.deb
Copy, paste, and Bob's yer uncle.
Oh and there's a Project Looking Glass 1.0 LiveCD as well, it seems.
