I caught this reportedly on BBC radio 4 yesterday . Tents made from cardboard , aiming specifically at the festival goer rather than anyone else. The designer came up with the idea after seeing loads of cheap tents brought and later abandoned at festivals such as Glastonbury. To be fair even he agreed it would be better for people to actually buy a decent tent and reuse it but this is aimed at those who perhaps can't or won't go down that route.
