My X-Seed 4000 post reached the front page of Digg’s technology section today… the page has received about 5000 hits in the past seven hours, pretty cool. (Update: the final traffic count was about 25,000 unique visitors in the single day that the post was linked from digg’s front page.) In honor of this, let’s brainstorm structures significantly bigger and more exciting than X-Seed:

1. Space Pier
2. Space beanstalk
3. 100km-aperture hypertelescope
4. Death Star
5. Borg Cube
6. some structures from Halo
7. Ringworld
8. A Dyson sphere
9. Deep Space Nine
10. Many proposed space colonies
11. Globus Cassus
12. Omega Point
