Lutron Pico wireless RF (radio frequency) controller can be used as a remote control that allows you to switch between scenes or di the lights (depending on type). Or by adding an additional mounting plate / wall station it can be used to create a fully wireless wall switch.
Wall stations can be stuck to any surface as they don't require back boxes or cables. They can even be used inside bathrooms to create your very own bathroom dimmer switch. If you don't want to wall mount your Pico then you can leave it lying around or there's also a pedestal for you to mount it in. The pedestal has a heavy base and is great for keeping safe on top of a desk or surface.
