We have two freebie items from Archangel Network, the main vendor location for which is at TARDIS region.
The first is a sonic screwdriver-inspired prop. It is seventeen prims and has animated energy-flow textures. A scripted version with cool special effects and other features is in the works.
Up next is a biggie. It's a flying saucer inspired by the Dalek time ships from the RTD era of Doctor Who. It is a mere nineteen prims, but it is quite large — 52x52 meters. A smaller, 10x10 version will also be given out through the vendors later this week. The saucer is no-modify.
If you like Doctor Who in Second Life and want some props to spruce up your land, these are good items to do just that.
