Paulus,
I actually missed the house of cards, so I can't have an opinion on it. I think that what we're being opened up to with this project, more than others I think, is a relatively young artist who still hasn't fully matured in his creative process. He's letting us see a lot of unedited ideas [or they just feel unedited]. It's like being at a brainstorming session except that it's part of the process and some can say art in itself.
Like I mentioned earlier in a post somewhere, I take a very different approach to conceptual art as there is a lot that I could never enjoy. For example, during the first party, some people performed to R Kelly's "In the closet"[?] album. At first I got the humour part of it and laughed, but the execution of the presentation was very amateurish and I could only imagine where it came from on a creative level. For me, that's the sort of idea that maybe I would come up with and bring to the table but not necessarily execute without really working on it. Maybe that's the difference between me and other artists.
Either way, I do think Gareth has the talent. I do think that good things will come from this project.
To end off, I once had the chance to hang out with Owen Pallett and roomate Steve Kado as they were shuffling ideas for a live performance show based on Dungeons and Dragons with tons of screaming and craziness. I remember thinking while there that those ideas should probably stay in the kitchen. Anyway, the ended up performing this thing and it was kinda lame. BUT, by then Owen was already working on his Final Fantasy project and sure enough most of the elements of that early idea for a performance are now implemented in the project... and this time around they're AMAZING.

Which also brings me to another point. This !wowow! movement isn't just happening in London, similar movements are going on in every city I have been in in the last year and some. There's definately a reason for it, but I won't get into it.
