The PYJAVAS Presentation Suite consists of an indexed slideshow of HTML web pages all prepared using the "webprog3" Editor. It is a simple alternative to apps such as Powerpoint. If you require clean, simple, vanilla presentations which are fairy easy to produce, then this app might well help you out. The screenshot on the left shows a webpage which took no more than minutes to produce.
However, if you are technically-minded, you can create more sophisticated web pages with links to the Internet etc., and even real BROWSER APPS for presentation.
