Tristan and I have an oversized quarter maze (actually 9x9). The base is made out of loft flooring which fits together nicely and comes apart into manageable pieces. The walls are made out of 12mm MDF which _is_ readily available in the UK. Shame we don't have a mouse to run up and down it - yet! Regards, Rafe p.s.
