I adored stamp sets when I was a kid. My grandmother got me an inking set where you could basically paint ink onto a stamp and transfer a full-color scene onto paper, rather than just an outline. It was awesome.

Esty seller MemiTheRainbow keeps the stamp-loving alive with her delicate, hand-carved Pac-Man stamps [via Technabob]:

Besides Pac-Man, you can find hundreds of quirky stamps and accessories in MemiTheRainbow's main shop, including a Space Invaders stamp set.
