Xccj had his, so now I should keep a log of what I want.
1) Weighted Storage/Companion Cube
If I make a WSC, I'd make it light up. If I make WCC, it'd just be standard. I can find enough plate to make the stripes light up.
2) Microcity scale anything
I am fascinated by micro, being that I personally have limited parts in system. I can envision a whole table layout, using 8x8 plate as my base, either baseplate or regular plate. Nearly anybody could submit an 8x8 plate of any standard color, and we could just combine them. Imagine a playground made by fifteen different people, or even a 16x16 Dome building.
3) Sounders FC on a soccer pitch
I could make all XI starter players of the 2011 Sounders FC team. Pipe dream, but I think it'd doable.
4) Mata Nui stone
I think I could generate one similar to my cube, it'd be simple and unique.
5) Mata Nui island (collab. project)
As you might be able to tell by now, I'm a -huge- System builder. Not in popularity, but in preferred building style. My boss, Dan Parker, suggested to me at BrickCon 2010 he wished to build the island of Mata Nui as a sculpture. The size he wanted was outrageously large, TOO large. For his idea to work, we would need at MINIMUM 90 15x15 baseplates, in length alone. We want to build much smaller than that.
It may happen this year, it may happen next year, it may happen in 2013 assuming we all live, but it's -going- to be built. It's too awesome not to be.
And yes, that'll be a huge project, regardless of its scale.
