Well I can't participate, but I'll post mine anyway because it'S rather.... large? I present the Kerbal Orbital Space Station (KOSS): It has the equivalent of 7 and 3/4 Rockomax Jumbo 64 tanks, living space for 21 kerbals, enough power production to light up nearly 6 ion drives simultaneously, so much monoporpellant I won't even bother counting it, enough stored electrical power to keep going at current electricity consumption for probably about a kerbin year, 5 dockingports at the fuel bay for direct refueling, 9 dockingports for other ships, 4 probe sized dockingports, a kethane processing facility and a fully equiped laboratory. The whole things weighting 500t and I don'T even bother with the part count. I'm running on windows 8 64bit, 8g of ram, crossfire video card AMD radeo HD 7670M 2g dedicated + AMD radeo HD 7660G integrated, AMD A10 2.3GHz, and I'm rolling this thing 1.5s per frame at the lowest graphic settings. It's ridiculously big, but I had a lot of fun building this, until the docking took about an hour to do. But yeah, it took 13 flights to get all of this up there. I also attached 2 SpaceTech single kerbal escape pods and a Dragon capsule, as an escape purpose. That doesn't puts enough place for all of the 21 crew memebers, but I could always attach two other dragon capsules if I felt the need to. I also have a Kethane tanker attached but thats not the purpose here. So yeah, too many flights, I guess I can't participate. But it's still nice. I'll drop a few more pictures of the assembly: the solar modules were so big I had to go with multiple docking ports, even with the quantum struts they'd just rip apart. Added the fuel tanks and the batteries Had a hum... minor dysfunction while adding the lab module (let's appreciate KSP's debris naming methods) Finished products before any ship was docked. Heavy. So yeah, large station.
