Production studio abstract:groove and advertising agency DLV BBDO have created a mesmerising promotional film for sports clothing brand Freddy by using  a clever combination of kaleidoscopes and gymnasts.

No post-production was used to create the kaleidoscopic effects seen in the film. Instead, abstract:groove designed and built four thaumascopes varying in shape and size in order to capture the footage.

Gymnasts from the Italian National Team of Rhythmic Gymnastic "le Farfalle" then performed within the thaumascopes for abstract:groove to capture on camera.

Prior to filming, abstract:groove studied small scale models and then simulated the movements in CGI to determine how well they work. You can take a look behind the scenes to find out more about how the film was made by watching the video below.
