PowerPoint slides are a given for any type of presentation these days to such an extent that we have all seen the same slide designs thouands of times. If you want to ditch the same basic PowerPoint template you've been using for the past several years and you need some fresh design ideas, Slidefinder.net is your friend.

Essentially, Slidefinder crawls the web for PowerPoint presentations based on a keyword or words you provide. When it finishes crawling, it presents it's findings as thumbnails. Postion your pointer over a thumbnail and a summary for that slide and the presentation it belongs to appears. When you click on a thumbnail, Slidefinder loads thumbnails of each slide in the set. You also have the option to embed a preview of the presentation in your own site.

Slidefinder can also be added as a search engine in your browser and as an add-in for PowerPoint.
