OfficeOne TransparentShow

PowerPoint is a very useful, very popular presentation tool that is used by many people to display multiple slideshows in both personal and professional situations. OfficeOne TransparentShow is an add-on for PowerPoint that enables users to make a particular color transparent in a slideshow, making it possible to have the slideshow appear on the desktop.

An easy-to-locate option that isn't lost among the standard PowerPoint interface

A common problem with add-ins for PowerPoint is that finding the new option can be extremely difficult, the standard PowerPoint interface can be complicated and provides multiple menus and options. Fortunately, OfficeOne TransparentShow is quite easy to find and the button is displayed clearly in the animation section of the interface.
When users select the new option provided by the add-on, it displays a small window with one options. A color selection is option is the only option available, it allows users to select and save a color to be disabled during the slideshow, instead appearing as transparent. If this is used on the main slide color, the desktop will be visible underneath.

Only one real function that is extremely limited, making the add-on quite basic

While the function provided in OfficeOne TransparentShow is relatively complicated, allowing users to disable a color and enable the desktop view beneath, it doesn't change the fact that it is the only thing it does. The add-on can enable users to make their desktop part of the presentation, which does hold some potential.
Unfortunately, OfficeOne TransparentShow only allows users to select one color at a time. The lack of multiple color support means that users have to be carefully how they select the color to match the slide and the background, otherwise the main feature won't work.

An interesting idea that could be improved with more colors being supported

The simple nature of OfficeOne TransparentShow is its biggest problem, while it is interesting and potentially worth experimenting with, it only works on one color at a time. That drastically limits the use of the tool and might make users wonder if it is worth installing at all.
