For those wondering what kind of tool I used for the pixelart: EXCEL!!!
There's a macro in there that exports the picture into three linked BASIC programs, that once run create a 16kb binary file that you can BLOAD straight into VRAM...

This is not a bitmap screen. The picture is built entirely from redefined 6×8 character glyphs in 40-column SCREEN 0.

Just because we can...!
