Last month Tech Monthly asked you to send in your images of construction. Our favourite (above), by Gareth N Price, captured two swans in the act of building a nest - check the best of the rest in our online gallery.
This month we'd like you to submit your photographs on the theme of navigation. So whether it's a dung beetle making its journey under the stars, a ship charting a course across the seas or a clever composition featuring GPS, share your shots and tell us how you captured the scene. Our favourite will be shown in the March issue of Observer Tech Monthly.
To submit your images click on the blue Contribute button or, if you're out and about, you can download the GuardianWitness smartphone app. We will print our favourite in the next issue of Tech Monthly and compile an online gallery to boot.
Closing date is 24 February 2014.
