I ended up playing with the Portal 2 editor the exact same way as with Minecraft, I build machinery and circuits and then struggle to find a practical use for them. So for a change I built something that already exists in the Portal 2 campaign but can't be done in the editor (easily).
A floor button with a timer, the puzzle isn't much but it does the job illustrating the potential use.
