Preact Nanobots

What kind of microscopic nanobots live in your bloodstream?
Hopefully none.
But if you have to have one, this little Preact bot looks like a helper more than a destroyer.

Made for an Egghead course on Preact – a powerful, tiny version of the React framework.

I've also been told it looks a lot like the robot from Portal? I've never played Portal, but must have been subconsciously channelling their style ¯\_(ツ)_/¯
