Using random objects to build homemade hand drums or maraca-style instruments isn’t new, but the team behind the ongoing Electronicos Fantasticos project takes the idea of repurposing unwanted materials to an imaginative level. Led by Ei Wada (previously), the Japanese musicians have spent the last few years recycling retail scanners and their barcode counterparts into synthesizer-like instruments, capitalizing on the product’s original function to produce rhythmic tracks and samples. Their recent design adds a playful twist to the concept by attaching the plastic devices to miniature skateboards that roll across ramps and down flat surfaces printed with black-and-white stripes. In addition to the musical component that’s similar to scratching an LP, it’s worth watching the group’s performances as they slide and riff on different barcodes, which you can find on Instagram and YouTube.
