Have you ever wandered by an empty room at a school and seen an inviting-looking chalkboard inside, just begging you to deface it?
Maybe that’s what photographer Alejandro Guijarro did. Maybe he created these mysterious, chaotic, attractive images himself. Though maybe he just walked by open doors and happened to stumble upon these chalkboards, covered as they are with arcane tapestries of mathematical symbols and eraser-mark patterns like aquatic landscapes. Check out his ongoing series, Momentum, and decide for yourself!
