Thanks to Ian McM we now have scans for another LEGO World Show, from 1984. As its date positions it between show 4 (1983) and show 6 (1985) and we already have a show 5 (1984) programme I am not sure what number show this is from!
The wallpaper repository is still being updated: I've added PoP and Racers (2010) folders along with various others. There's no easy way to see what's new though: perhaps that's something I need to add.
Finally, I imported the minifig data from Bricklink today, which now includes a full set of data for the PoP sets.
