Google's Doodle — the design on the search engine's minimalist homepage — is a playable Rubik's Cube today.
The puzzle and icon of 1980s pop culture was invented in 1974, but the reason Google chose today, 5/19, to feature the Cube is because of the 519 quintillion configurations of the cubes.
The head of Google's doodle team (yes, there is a team dedicated to just this feature) told Wired that they had wanted to do a playable cube for some time, but didn't think web technology to handle it was widespread enough, until now.
With support for CSS 3-D Transforms in most browsers today, the team felt comfortable going forward with its idea.
To manipulate the cube, mouse over the face you wish to rotate, click and hold the mouse button and drag the cursor in the direction you want to turn it. Users may also rotate the view of the cube by clicking and dragging in the white area surrounding the cube.
Google is making the source code for this doodle available for those who want to remix it. Those interested in playing with the Rubik's Cube after today can find it — and all past doodles — in the archive. Past interactive doodles have included a playable Pac-Man tribute on the game's 30th anniversary and, last year, an 8-bit Dr. Who game celebrating the series' 50th anniversary.
