This dark neon wave lines background for PowerPoint draws a few thin glowing sine curves in pink, blue and purple across the lower half of a black stage, with their light pooling on the floor below like a reflection. I kept the top half of the slide empty, so titles and bullet points sit in clear black above the waves. Made for tech, music and audio slides, and for wallpaper.
