A friend gave these to me at a music festival without telling me what they do and I was blown away. They turn every light and laser into hearts, creating a thin halo/prism around the crowd. They make the world more beautiful and definitely a more amazing place. These prisms I mentioned are the closest I've ever seen to images of hallucinogens with no real substance, which is amazing because all children, adults and seniors deserve to make the world look this beautiful. Great for Christmas lights too!
