Made for the Dragon 32 demo "Dragon Pepper" released at Gerp 2020. The resolution in this particular graphics mode is 128x192 pixels, and it also forces you to use one of two predefined 4 colour palettes, described on Wikipedia as "rather garish". Using the blue/red/green/yellow palette also sets the border colour to green.

You can view a recording of the demo running on real hardware here - in the video the picture looks like it uses some sort of flicker/interlace mode but that's just a side effect of the composite video capture: https://www.youtube.com/watch?v=CF3u4OQr4A0

If you want to try it in an emulator or on a real Dragon computer, you can download it from Pouët: https://www.pouet.net/prod.php?which=84818
