Google has combined with music video pioneers OK Go and dance troupe Pilobolus on an HTML5 Chrome experiment called All Is Not Lost.

The video is filmed through a glass floor, with the dance troupe and musicians themselves creating a series of kaleidoscopic shapes.

As the video continues, though, the Google Chrome windows start to change size and split apart. 

Finally, the dancers combine to create letters, spelling a phrase entered by the viewer before starting the video.

According to the Google blog, "OK Go are well-known for their delightfully creative music videos... which have become extraordinarily popular on YouTube.

We’re excited to collaborate with them on another project that finds its natural home on the web.”
