Create a 'Frosted Glass' effect in your PowerPoint slides using PowerPointLabs

'Blur Selected' feature of the Effects Lab (one of the Labs included in PowerPointLabs) can be used to create a frosted glass effect by adding a blur effect to the selected area. 



To use the feature, first draw a shape over the area to be blurred, select the shape, like so.


Then select Blur Selected from the Effects dropdown menu and choose the blurriness level to use.

This feature is especially useful when you want to show some text to appear over a picture background without the details of the picture interfering with the readability of the text. Here are some examples:
