'Full Secs' is an ongoing animation challenge being curated by London-based studio Animade. The goal is for animators to submit a five-second microfilm - a one-second animation 'sandwiched' between a title card and an end slate.

Some are strange, some surprisingly clever and most are rapidfire gags that are over before you even get a chance to realise what's actually happening.

The challenge has been running since September 2012, and as the project approaches its one-year anniversary hundreds of videos have already been submitted.

Here are five of the best.

Iceberg by Mantas Bačiuška

Breaking Dad by Zerox

To Kill a Mockingbird by Philip Vetter
