Blood drop trail
A Blood Drop Cursor Trail would add a dramatic and vivid touch to the web page screen, evoking the rich color and vital significance of blood. As you navigate with your cursor, a deep red droplet character, which could be whimsically named "Ruby," would trail behind.
Ruby would be a striking drop of water, colored in a deep crimson, reminiscent of the life-sustaining fluid that flows within us. The trail left by Ruby would consist of smaller red droplets that appear to bead and then gently fade from the screen, like drops of blood dissolving into water.
