I suspect that it isn't that since he was talking about a monolith-shaped prize that ACC is funding for his old school in Taunton, and saying the picture looked like it.
I have exchanged mail etc. with him a few times in the past, so it's possible that I've been confused with another Marcus or something. If anyone has recently forwarded a Monolith picture to him, it looks like the wires have got crossed. I'll phone back tomorrow and see if I can sort it out.
