Not everything that ends up in my trash bin is a failure, because I happen to like this gold and silver PowerPoint cover slide template quite a bit. So much so that I’ve been incorporating elements of it into other presentations for a multitude of different projects over the course of many years. It features a transparent glass globe placed behind a series of thick chrome cables, along with plenty of open space to the left for the title information of the presentation. Personally, I think it makes a rather strong impression for a presentation cover slide.
If you happen to like this style of background image, I have some variations available which can be seen here – there are a multitude of different combinations available that should fit any situation nicely.
