Twister theory has, as a long-term goal, the appropriateunification of space-time structure with quantum- mechanicalprinciples. Although the goal remains remote, we already see that itgives rise to some basic non-local aspects to the geometry. Thetheory is rooted in some classical geometry and leads to descriptionsof physical fields in terms of holomorphic sheaf cohomology.Some recent developments relevant to high-energy physics will bebriefly described.
