Honestly, how cool is this? Swedish artist Johan Karlgren, also known as Pappas Pärlor, has been creating street art with his favorite 90s video game characters and pop culture icons. Homer Simpson walking backwards into a hedge, Mario Cart characters racing along the beach, and Sonic the Hedgehog skating the underbelly of a freeway pass . . . so nostalgic! Can you guess how he creates that 2D, pixilated look? Perler beads. YES, perler beads! Genius.
