For a developer audience, I have seen people use plain old browser tabs to successfully run engaging workshops. That way, all of your slides can be any web pages.

You can use Ctrl+Tab (Shift+Ctrl+Tab) to cycle between the "slides". You can store the whole presentation in a dedicated bookmarks folder. Then, use "Open all in a new window" from the context menu of the bookmarks folder to run your presentation.

Maybe in a business-oriented setting that would be labelled as "lazy", but for me it feels bold.
