Apart from the raster bars and lissajous curve all other demos can be interacted with via mouse

Example #1: Scribble & color cycling
Hold down left mouse button to cycle the colors (the current palette is also always shown in bottom-left corner). Nice, powerful oldskool effect, which is actually easier to do with these indexed, non-RGB pixel buffers[1]
Example #2: Lissajous bobs
The spheres are actually 2x2 tiles of 8x8 pixel sprites with one color slot chosen as transparency. Drawing 100 spheres here, but could be a lot more...
Example #3: Raster bars
This oldskool effect is achieved via HSYNC interrupts only, i.e. no lines are being drawn — for every single pixel row we simply change the color value of the first palette entry. The text is also only being drawn once, at startup...
Example #4: Particle system
Simple particle system (2k particles) with the emitter position linked to the mouse. 6% probability for larger particles.
Example #5: Random pattern
Classic oldskool generative art, here by defining 4 custom bitmap font characters and then drawing a single randomly chosen char per frame
Example #6: Bitmap font editor
Select a character on the RHS to edit in the left box. Left click to set a pixel, right click to clear it. Press Delete to clear the char entirely. The system supports proportional width fonts and the little red triangle can be moved horizontally to adjust the width of each char... Clicking on the Save button will download a JSON file of the font's binary data (9 bytes per char: width + 8 data bytes)
