You found the link to the easter egg of this site. From here you can download and play this cute little skiing game written in assembly language for the ZX Spectrum. Steer the penguin to avoid llamas and cacti while collecting coins. You'll need an emulator to run it (unless you have an old Spectrum lying around), and I would recommend Fuse, the Free Unix Spectrum Emulator, which can be found here.
Stay tuned for more experiments in 8-bit programming.
