The graphics tone remind bit of "Beneath a steel sky" and the review suggest it's a modern take on retro adventure. And the price seems right, I might have to get this.
Of particular note are the visuals which atleast look like they've done a proper attempt instead of the shoddy work seen in most of every 3D game except maybe Fallout 3 where the LOD in few places approached to that what a properly done 3D adventure requires. Since that's so expensive it's just more economical to do 2D. This among other things leads me to believe that 3D adventure game is the most expensive single player game genre. So it's not that the genre nearly died temporarily due to lack of players but due to economic constraints. It's just cheaper to do shoddy 3D and hope the 3D is enough to keep the users interest vs doing a proper 2D game where every screen has to be done tastefully to keep the player interest up, atleast if it's a game of tedious and weird puzzles. (The review sounds like that might not be the case for this game which is why I have to check it out)

From Wikipedia:
Machinarium was developed over a period of three years, by seven Czech developers, who financed the project with their own savings. The marketing budget for the game was a scant $1,000. Machinarium won the Excellence in Visual Art award at the 12th Annual Independent Games Festival.
