Alternative graphics in XOR never really caught on in the same way they did on Repton 3 - nevertheless, the Level Designer package on the Beeb featured a perfectly capable Icon Designer.
The graphics presented here are extracted from the Beeb version of XOR. They came from the XOR Level Designer floppy, and from the extra floppies that J Connor kindly donated. I knocked-out a quick BASIC program to turn them into individual PPMs, and then converted them to GIFs with Paint Shop Pro.
On the Level Designer disks, Icon files are prefixed with an I - for example, I.NORMAL. I'll write-up the file format if anyone is interested.
