+S+ Nixi Tube Clock & Countdown Timer <Box>

These are very nice, they look perfect, can be scaled and they're easy to mod. I was able to script mine so it'll display a random value that changes every day (it'd be nice if they came with a full perm version of the digit textures, though. I was forced to use llOffsetTexture and that has a built in delay, but it works for my purposes).
