The Machine is a fun little puzzle game in which you build conveyor belts to move coloured blocks around a level and into a dumpster. You've given only a set number of pieces, so it's essential that you place each one down in the correct position.

Once the concept is understood fully, new elements are added to the mix such as different coloured blocks, machines that split blocks in two, and cannons for firing blocks over gaps in the floor. The best method for completing each level is usually to fill in all the spaces that are obviously, then experiment with your remaining pieces to connect it all together.

There's a demo available, although it's rather brief and only barely shows the concept off. You can grab the full game from Impulse for $8/£5.
