SpiNNaker (Spiking Neural Network Architecture) is a computer architecture designed by the Advanced Processor Technologies Research Group](APT) at the School of Computer Science, University of Manchester, led by Steve Furber, to simulate the human brain. It uses ARM processors in a massively parallel computing platform based on spiking neural networks.

A spinnaker is a special type of sail that is designed specifically for sailing off the wind from a reaching course to a downwind, i.e. with the wind 90°–180° off bow. The spinnaker fills with wind and balloons out in front of the boat when it is deployed, called flying. It is constructed of lightweight fabric, usually nylon, and is often brightly coloured. It may be optimised for a particular range of wind angles, as either a reaching or a running spinnaker, by the shaping of the panels and seams. Some types of spinnaker can be carried by the side of the boat, but still in front of the mast. This is called "flying a shy spinnaker", and is used for reaching.
