Studio AKA (http://www.studioaka.co.uk/) are an animation agency who have worked with companies such as Green Flag and ITV. The work they produce is generally 3D modelled characters such as the ants from Green Flag, although some of their work is 2D Abstract movements.
ITV - I'm A Celebrity Get Me Out Of Here
STUCK ON A SUNDAY
National Palook - Swan Lake
Clearly very talented animators, I love the way the characters move and feel alive.
