Halloween is a very popular holiday in our house. We live in a good suburban neighborhood, we get a good volume of younger kids, and not too many older kids without costumes carrying their pillow cases and expecting a big haul. So we do it up right, decorating the front of our house in a fun (not too scary way).
Since the local Spirit Store has already opened, we’re beginning planning now. We’re looking at a science-fiction theme this year, so the geeky gears are already turning. One idea involves building a robot (styrobot?) and planting a LCD display on the head, then recording a loop of interesting/funny commentary with appropriate special effects. I’m also thinking about building a tunnel with PVC and black plastic, stringing a bunch of lights down it, adding strobes and a fog machine for a "warp-speed" effect.
But what else? Any other good, and relatively easy-to-build ideas out there for a fun, science-fiction display? Can’t be too scary (we get a lot of younger kids), but it can involve interesting uses of technology (we have the use of three laptops, one desktop, an LCD projector, and various other A/C components). Leave your ideas in the comments, thanks!
