Just bought and started this brilliant this game, <a href="http://machinarium.net/demo/" target="_blank">Machiharium</a>. We've probably all played the Samorost games in the past, and as Machinarium isn't necessarily a new game (it's new to me) you may have already played it yourself.
It's available for Android and Windows, and well worth buying in the interest of supporting the creativity and imagination of smaller developers.
