While Vinh wasn't ready to spill too many secrets about Lascaux's next app, he did say that "it's still about collage," and that the company's goal with the as-yet-unreleased sequel was to empower users to create "regardless of whether you have artistic talent."

Existing Mixel users can save any mixels they created from within the app by tapping the Share icon beneath each one they'd like to save. The company adds that "in the coming weeks, we'll also have a simple way for you to download all of your mixels in a single bundle."

Once the Mixel network shuts down in September, the app will no longer function at all, the company says. When that happens, the webpages for each mixel will vanish as well.
