This is Nyan Cat for the BBC Micro by CRTC. This demo was released at the Sunrise Demo party in 2011. See the following pouet page for more info : beebnyan by CRTC You can download a SSD containing beebnyan from that site to either run inside a emulator, or on a real BBC Computer.
Can you watch the video to the end?
I recorded this video on a real BBC Master 128. The original sound output from the BBC wasn’t great, so I recorded the audio direct onto my laptop and overlaid the sound onto the video. The BBC isn’t known for its audio quality!
You may also notice I have copied the demo to the :0 ADFS hard drive. My :0 is a 512mb CF card attached to a RetroClinic Datacenter USB/IDE interface.
