Haven't seen this on here yet, and thought it was a pretty innovative way to delay creep spread by QXC. QXC uses a bunker at 4:10 as part of a gasless one rax expo into double gas reactor hellion build, to delay creep spread. The bunker in combination with an scv repairing it and the hellions that arrive soon after, combine to make it alot more difficult for zerg to spread creep without forcing extra lings.
This looks like a pretty cool idea which potentially could be explored as part of a standard strat.

Introduction
With the recent enhancement to the Queen's range, Zergs in ZvT have been consistently opening with 4 or 5 queens, limiting the ability of a reactor-hellion opener to deny creep spread. This greatly-improved creep spread poses an enormous challenge for aggressive styles of play. The archetypal aggressive Terran, Kevin “QXC” Riley, has developed an interesting approach to delaying this creep spread.
The Bunker Set-Up
1: QXC starts building this bunker at ingame-4:10, after the expo-CC and double-gas.
2: The first spawn of zerglings will pressure the bunker. QXC micro-managed his marines exceptionally, buying time until he could load the bunker. Be prepared to do the same.
3: Zerg may attempt a zergling runby before finishing speed. Be willing to lift your expo-CC until hellions are ready.
4: The SCV stays there to repair. You want the SCV a few squares behind the bunker so that Queens or speedlings take some extra damage trying to snipe the SCV.
5: Place the bunker such that the marines can cover the full breadth of the choke (see example bunker below - the yellow-hp SCV is within range of the bunker).
Managing Creep
Once the Hellions join the bunker, use the hellions to manage creep spread.
2: Retreat to the bunker if the hellions are at risk.
3: Because your SCV is still by the bunker, you can repair your hellions erstwhile.
Zerg needs to break out to take a third and continue to spread creep. In most cases, this required the zerg player to make more non-drone units than he wanted.
