Last month’s Tech Monthly project drew a fantastic response, with nearly 300 entries on the theme of “clusters”. Our favourite image, a huddle of newly hatched spiders, was taken by clenchpen2 using a Canon 60D, 60mm macro lens, f8 1/125, ISO 400. See a selection of the best images in our online gallery and browse the entire range of submissions online on GuardianWitness.

Fancy seeing your picture in print? Join our next science and tech GuardianWitness project! We want you to submit your photographs on the theme of ‘networks’. So whether it’s a web of neurons, the building of a new train line, an interesting take on social media or simply a raft of sea otters holding paws, we want you to send us your pictures and tell us which kit you used to take the perfect shot.

Share your images by clicking on one of the blue 'Contribute' buttons, 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.

Closing date: 20 November 2013.
