More Information

Open Source Live Visuals
Visualist? VJ? What’s the difference? Who cares?
Live versus pre-rendered
Open versus closed source
From gnu.org:
Free software is a matter of liberty, not price.

glitchNES
What it does: RAM corruption causes graphical glitches ons screen, similar to hardware circuit bending.
How you can use it live: works well as an abstract background layer

galleryNES (0.1)
What it does: displays still background images that you can swap through
How you can use it live: still images such as logos or full screen art

galleryNES 0.2 / NES Logo Program
What it does: similar to galleryNES 0.1, but adds color cycling and scrolling.
How you can use it live: as a moving foreground layer for a number of things, and for small color cycled animations.

NES Movie Player
What it does: plays short movies via bankswitching graphics in the NES
How you can use it live: play short clips straight from hardware

Software and Hardware options
NES development cartridge
RetroUSB PowerPak
Emulation

Development Cart
Benefits:
Easy to switch out PRG / CHR chips
glitchNES: easy to do further hardware bending to supplement effects
Fun / awesome / cool factors

PowerPak
Benefits:
Easy to change tile sets
Easy to make multiple copies of the program with different effects
Challenges:
Looks different than dev cart and emulation

Emulation
Benefits:
Easy to change tile sets
Easy to make multiple copies of the program with different effects
Challenges:
Different emulators provide different results

Live Setup
Mixer - used to mix between multiple video inputs
I use: Edirol V4 (pictured)
Monitor – used to preview a single channel
Small, rugged, & color hopefully
Hardware:
Consoles – concerns with older parts
Computers – concerns with outputs
Projector:
Resolution, brightness, throw

Live Setup: Putting it all together

Performing Live: Quick demo
Keeping the musician in mind
Beat matching and counting
Mixing versus chroma keying
Effects
Layering:
