ZX Spectrum Beeper Demo by ataritufty, recorded from a ZX Spectrum Next

In another video (   • ZX Spectrum Beeper Demo by ataritufty, rec...  ) I ran this on original hardware. Here it's run on a ZX Spectrum Next, a modern recreation of the machine. The video and audio was captured using a Cloner Alliance Box Pro, which converted the 50-fps per second video to 30 fps, which loses some of the border effect. This amazing code from ‪@ataritufty‬ is only around 6kB.
