First map is some jungle themed temple as well as my first attempt at trees. The second image is underneath one of the later spawns, the portal room.
Each portal would take you to a different guest map (freebuild), these maps would be reset as needed. They were 256x256 in side typically. Once a guest had shown /some/ potential in freebuild, we'd promote them to builder. They'd then get two personal maps, an 01 and 02.
