Hey Mat

Looks good mate! How did you go about animating the baloon? I would have either gone using a hair system attached to the curve for the string and a rigid body witha - gravity system constrained to the string.

Its got a real nice feel to it, something seems a little off but thats possibly the straight on camera angle not letting you see if its making subtle backwards and forwards movements.

Your making some headway into your project so far mate, hope that it get's approved by the lecturers.

Drop me an e-mail if you want to chat about your final year project, as I went through mine last year, athought it mighe be different what with different unis/courses etc.
