Canadian musician Grimes is launching an “intergalactic children’s metaverse book.”

Announced Friday at the Avalanche Summit in Barcelona, Grimes, also the mother of Tesla (TST) CEO Elon Musk’s children, said the project was part of a $100 million initiative from OP3N and the Avalanche Foundation meant to support the development of projects related to art, entertainment and culture on the Avalanche blockchain.

“When I first got into Web 3, this was the kind of project I was hoping to see,” Grimes said in a statement. “I’m very excited to be partnering with [OP3N] to launch a series of educational art for babies and small children with the goal of creating a profound experience for babies that is also deeply meaningful to adults.”

The artist previously sold around $6 million worth of digital art after putting up a non-fungible token (NFT) collection in March 2021. Grimes was also featured in TikTok’s NFT Collection.

OP3N describes itself as a launchpad to empower creatives in Web 3 and is partnering with the Avalanche Foundation to launch the $100 million initiative. Coined “Culture Catalyst,” the project will include the Grimes book project.

The initiative follows a $10 million seed funding round for OP3N, co-led by the general partners of Galaxy Interactive and BRV Capital Management. The Sandbox’s Sebastien Borget and Axie Infinity co-founder Jeffrey Zirilin also backed the round, according to a press release.
