How to create Lightning

In my Proposal the character weilds lightning. I'm going to look in to different ways of creating this effect.

A way to create lightning is through the programme, Adobe After Effects.
Here are some tutorials that I found quite useful.

There is also advanced ways of creating this effect.

In the Film X-men ( SINGER, B 2000) one of the characters, Storm, has the ability to eject lightning from the sky to oblitorate her enemies.

The inspirtaion in my film actually came from Bioshock, where the electricity comes from the characters fingers.
