This is a base I made some time back but never got around to posting.
The walls are made from card board and the rocks are carved from foam board. I used some plastic packaging for the window and every thing inside the windoe was made from styrafoam pizza base. The reactor rods are glow sticks, the back opens so you can change the colour of sticks used.
The panneles are pizza base wire and beads.
The outside walls were covered with a polyfiller and pva mix that was stippled on with a stiff brush, then every thing was painted and a small hole was cut in the windo so Kittys foot can go through as if phasing.
Its not as good as some of my bases but I hope you guys like it, let me know.
