introduction to twistor theory

MathematicalPhysicist

does someone know where may i find itroductory information about
twistor theory?
im asking because the website of twistor theory with introduction
paper is currently not working.
thanks in advance.

wolram

here are a few to get started on hope you find
some of interest,

thanks.

There exist also a theory called Supertwistor theory, that is twistor theory with the incorporation of supersymmetry

LoopQG what is the link to the regular site?
(which you say is not working right now)
wolram, that 1987 paper by Penrose that gives a
personal account of how he arrived at twistors
had some interesting and understandable parts---
thanks for a good reference!

as far as hardcopy goes
for introductions to twistors
selfAdjoint says he has Huggett and Tod
which is one of halfdozen introductions mentioned in
the Witten paper,

as introductions the paper recommended numbers
15, 28-32 from its list of references:

I havent ever laid eyes on any of these. But the fact that selfAdjoint already owns [32] Huggett and Tod is something of a recommendation.

I am still curious to know if anyone has found some sort of introductory twistor textbook ONLINE. Could one be buried in PF's "napster" links?

thanks LQG, I tried it too, and just got a blank-white page
if you try again later, and it works, please let us others know
I will do the same

Here's info about the Penrose transform, that I think is of central importance in twistor theory:

By the way, what's an ambitwistor space? Perhaps our old friend Ambitwistor can respond to it?
