A "Cats in Space" themed LED lightsaber battle is scheduled to take over St. James Park in San Jose on Saturday.

Toronto event producers Newmindspace, who threw a bubble-blowing party in San Francisco's Dolores Park in 2015, have been throwing lightsaber battles internationally for years, including one last December in San Francisco's Justin Herman Plaza.

Newmindspace's battles used to have a Star Wars theme until Lucasfilm came calling; post-settlement with the Bay Area company and they're now called "space battles" and can't technically refer to the fighting weapon as a lightsaber.

For $10 participants will be reserved lighted stick, with a portion of the proceeds donated to Make-A-Wish Foundation.
