This Harry Potter-themed clock adds a splash of style to your desktop, but you probably won't be entranced by this feature-light application. Harry Potter Clock resides in your system tray and launches with promotional wallpaper and an analog clock complete with Harry's image. Like a classic grandfather's clock, you can hear a ticking sound every second. Thankfully, you can adjust the volume. You can set the clock to play a slightly haunting sound every hour, half-hour, or quarter-hour; during exit; when minimized; and upon running the application. However, compared to other PC clocks, you can't set an alarm nor can you select another sound. Harry Potter enthusiasts may find this 15-day trial application fun to use, but most folks won't be impressed.
