Blob Opera is an experiment in machine learning by David Li and Google.Google

For fans of the interactive treat Blob Opera, its creator has updated this addictive time-waster. Now you can take all the fun on tour by picking a city for the singing blobs to perform in.

Created by David Li with Google Arts and Cultures, Blob Opera asks users to click and drag on a gelatinous blob that plops down on a virtual stage. A robust bass voice bursts out. Vertical movement changes pitch; horizontal alters the vowel sound.

Then another blob drops, this one a tenor. And then a mezzo-soprano. And, finally, a soprano. Before long, they're all harmonizing in a bizarre faux opera that sounds surprisingly alluring. You're the conductor.

Better yet, there's a new option to take the blobs on tour and be the conductor you always wanted around the world. The list of locations include the Blobpera House, London, New York, Mexico City, Seoul, Cape Town and Paris.

You can record your experimentation and share the results on social media.

Unlike Adult Swim Choir, Blob Opera can't be embedded here. But go to Google's site to try it now.

Have fun!

By the way, Blob Opera used real opera singers in its creation. Google explains:

Here's more about what Blob Opera is, how to use it and how it was created:

We developed a machine learning model trained on the voices of four opera singers in order to create an engaging experiment for everyone, regardless of musical skills. Tenor Christian Joel, bass Frederick Tong, mezzo-soprano Joanna Gamble and soprano Olivia Doutney recorded 16 hours of singing. In the experiment, you don't hear their voices, but the machine learning model's understanding of what opera singing sounds like, based on what it learnt from them.
