Congratulations to Jenny Downing who shared this incredible image of a curious snail as part of our equilibrium project. Take a look at the best of the rest with our online gallery of other top submissions here.
This month, we would like you to turn your cameras to images on the theme of Elements. From diamonds to helium balloons, share your photographs and tell us how you took the shot. Our favourite will be seen in print in the May issue of 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 Monday 28 April 2014.
