I created the following Spinning Wheel entirely on PPT. The credit for the training goes to “presentationprocess.com”.
If done correctly PowerPoint presentation is a tool that it has many possibilities and is still relevant. But I see many people dislike PowerPoint because of the new fancy tools that are taking its place everyday. But to be precise, PowerPoint presentation creation is fairly easy and most of all it is accessible to any computer device unlike the fancy authoring tools.
Now it totally depends on you how you want to use it and what is your requirement. I never miss any opportunity to learn creating something worth attention on a PowerPoint!
