Simply put, Heart Bubbles adds floating heart bubbles to your desktop. These bubbles can be popped with a mouse click, or you can just enjoy the effect of floating hearts on your screen. You can choose whether you want bubbles floating on the desktop only or over your windows as well. You can also adjust the bubble shapes and speed. This is a fun little app to give your desktop a bit of life. It could perhaps use more options for bubble shapes, however, and the bubble motion is not always smooth.
