Lego brick-building just went multiplayer and virtual in Snapchat. A free experience announced by Snapchat during its developer-focused Snap Summit livestream immediately overlays Lego bricks and models onto the real humankind with AR, but it also works with someone else throughout to try with you, or someone long-distance through the app. It’s one of a number of new initiatives by the increasingly AR-focused social mediate app, which also announced a bigger build-out of tools for AR shopping needs, and a partnership with Disney to layer AR effects at Disney parks.

The Lego news is a part of Snapchat’s bigger push for collaborative AR needs. Multiplayer AR has slowly been explored in some apps and games already, and Snapchat has explored some larger-scale people AR in public spaces that are specifically mapped to work. The multiplayer AR that Lego uses, silly a new Snap tool called Connected Lenses, points to where spanking collaborative AR applications could head.

Lego has already been glowing in AR, with its own AR-enabled brick sets and minifigures. The Snap experience, however, doesn’t require any physical bricks at all.

Other AR-focused affects, like Niantic, have been pushing more towards multiplayer AR recently. Microsoft’s new software platform, Mesh, is focused on collaborative cross-platform AR, too. It looks like Snapchat keeps pushing toward its own deeper AR needs as well, which could also lead to an ecosystem succeeding with AR glasses down the road.
