Hectic is a period 30 oscillator that was found by Robert Wainwright in September 1984. It is based in a reaction in which a queen bee shuttle is stabilized by a collision with a glider, which is reflected in the process. Two gliders shuttled in a loop between four queen bees makes up the complete oscillator. Similar but larger loops can be constructed.
While the reaction used in the oscillator is a compact way to reflect a p30 glider stream, it is not very convenient since the queen bee also relies on the glider for survival, and therefore gaps in the glider stream will destroy the shuttle. The buckaroo is more versatile, as it stable on its own.
