"Lode Runner" on Code Files

[cretz]

• As I was sitting viewing my VS code files w/ varying colors and line lengths, I starting thinking about "what if a little guy or stick figure treated this code as a vertical level"
• Basically this would be a tech demo or the equivalent of a screensaver or otherwise little novelty thing
• Cannot affect anything the user is doing (i.e. guy affected by scroll and tab change, not the other way around), and ideally is not too distracting (i.e. small character, could be only a few shades away from background color)
• Simple automated character that runs around on text lines, maybe doing different things on differently colored text, climbing/falling between lines, etc
• Good showcase of vscode extension capability
