Plagiarism or mini coincidence?

I came across a couple of interesting ambient ideas over Christmas (via Inspiration Room and Culturebuzz blog).  Both ideas are classic examples of  thinking outside the box (excuse the pun)! Just a shame they both thought of the same idea at the same time!

Here’s Mini’s ambient concept which dramatises the idea that if you were to buy a Mini for Christmas you’d have to ditch the box somewhere.

Then there’s Heineken where TBWA/Noboko have tried to capitalise on the successful walk-in fridge campaign from last year.

I reckon this is just an unlucky co-incidence rather than any act of plagiarism. What do you think?
