Trailer for Machinarium; in the actual game, clicking around in the right order initiates many of the actions you see here.

Machinarium is the latest stunning art game from Flash designer Jakub Dvorsky and his crew at Amanita Design in the Czech Republic.

At Jay Is Games you'll find a review, comments and walkthroughs. The review begins,

From Amanita Design, creator of the famously brilliant Samorost series, comes Machinarium, a game so well-conceived and implemented it can confidently launch as one of the best point-and-click adventures of all time. Machinarium is nothing short of a playable piece of art. Similar to Samorost in style and gameplay, you play a lone robot thrown out of the city working his way through desolate mechanical slums. Solve puzzles, find and combine items, and encounter loads of creative characters in your quest. Machinarium is one of those rare games you can't praise enough...

There's a playable online demo, and a full downloadable version for $20 (Windows, Mac, Linux).

In Indie Games' 2008 Interview: Samorost Developer Jakub Dvorsky, the designer discusses Machinarium and more.

If you haven't yet played the earlier games, here they are: Samarost, the Polyphonic Spree Quest for the Rest and Samarost 2, all free online demos.
