If you’re a fan of HTC’s slick Sense UI interface, HTC Home brings a little bit of that interface to your desktop as a combination clock and weather widget.
You adjust the size, the position, and the font of the widget as well as tweak the location for the weather and time. One of the fun little gems hidden in HTC home is the wallpaper changer. You can save wallpapers with tags inside the file name like cloudywallpaper.jpg and sunnywallpaper.jpg and HTC Home will change the wallpaper based on the weather conditions–you can read more about that feature in the documentation here.
HTC Home is open source, Windows only.
