Battery Doubler is a smart program that extends the lifetime of your laptop battery by decreasing the electric power consumed. This will give you at least 30% of extra battery life. The program can recalibrate a damaged battery and make it report time correctly.
Being a PC accelerator, Hare promises to speed up your computer up to three hundred percent of its original speed. Most of times, whenever I hear something like this, I wonder if it does what it says before or after I find the pot of the gold at the end of the rainbow, but this program is actually quite good.
Juggle Mouse incorporates a trail that follows the mouse pointer movement. The trail is composed by small images. You can change the position of the mouse trail and setup these effects: wobble, fast/slow move and translucent trail. You can create your own Juggle Mouse themes, but you can also load many of them from http://www.dachshundsoftware.com/jugglemouse/gallery/.
