If you search over YouTube, you'll find many people who have built one aspect or another of a lightsaber. There are things that look like lightsabers, but can't collide with each other. There are things that look like lightsabers, but can't collapse into a hilt. There are things that dump energy like lightsabers but don't fit into a dapper little hilt.

It may just be a matter of perspective, but if you spend enough time with the various options, you may well come away with a much better perspective on why you're never going to have anything just like them. You might think seeing the possibilities would make it more likely, but you'll also see just what it would take to be all these things at once.
