PixelStix, a St. Petersburg tech start-up founded by Matthew Walker, partnered with the SHINE mural festival  this year to deliver digital content that showcases the murals and artists that created them. Â
Pixelstix is a FREE app that can be downloaded on any smartphone. Once installed, users can touch their phone to the sticker on the mural and see the content associated with that sticker.Â
