Google announced of sharing the code of the Stanis?aw Lem doodle under the Apache 2.0 License. Google notes that the images and animations accompanying the doodle remains under the Creative Commons BY-NC-SA 3.0 License.
"The big difference between those two is that the first one allows commercial re-use, whereas the second one forbids it," blogged Marcin Wichary, Senior user experience designer, Chrome.
"Just like picking the right paintbrush and palette is important for all our doodles, so is figuring out the right technologies and proper user interface for those we want to make interactive. That's something I'm personally really excited about and that's why today I wanted to share that excitement and the entire source code of the doodle of Stanis?aw Lem, a sci-fi writer and philosopher with you - accompanied with an article explaining HTML5 technologies that we used… or didn't use," writes Wichary.
So take it for a spin, play with it, and if you do something interesting, find a flaw, or have a comment - feedback at email@example.com.
