I thought Francesca was looking tasty in this week's ep, also in the You're Fired clips afterwards talking about Sophie. She's like a cross between Stella from previous series and Gemma Atkinson.
As for the box I actually thought the original idea of a cube wasn't that bad on first impression, i.e. different sides for different functions and you flip it round (although quite how many distinct functions you could put on flat, identically sized faces I'm not so sure!).
I've gotta be honest, maybe because am not artistically minded but I am frequently amazed by how 'good'/inventive the products the contestants come up with in such short spaces of time are series after series. I know they get help from professional designers, but if you threw together some bunches of people who barely knew each other and asked them to design and build a new product in a day, how many of those groups would actually get big retail buyers to place an order?
(Of course it isn't a 'true' situation and you don't know what the production team gets up to off camera in terms of helping things along to make good TV, but leaving that to one side as a general concept the idea of doing what they do in that space of time would scare the **** out of me)
