In this setup, we build a live generative text field using a Text DAT and turn it into an evolving visual texture using Feedback TOPs. The result is a constantly shifting “data surface” made of random characters.

This can be used for:

• cyberpunk backgrounds

• audio-reactive visuals

• abstract data streams

• glitch / generative art systems

We generate a grid of random characters inside a Text DAT, send it into a Text TOP, and then use a feedback loop to make it evolve over time.

Instead of static text, it becomes a living system.

Step 1: Create the Text DAT

Create a Text DAT and name it:

random_text

This will store our generated character field.

Step 2: Create an Execute DAT

Create an Execute DAT and enable:

• Frame Start

Then paste this script:

Step 3: Text TOP Setup

Create a Text TOP and connect it like this:

• Set Text Source = DAT

• Drag random_text into the DAT field

Now you should see a full screen grid of characters.

Step 4: Visual Processing Chain

Now we turn it into something alive.

Build this chain:

Text TOP ↓ Level TOP ↓ Blur TOP ↓ Transform TOP ↓ Feedback TOP ↓ Composite TOP ↓ Transform TOP (final output)

Optional: Audio Reactive Version

If you want the field to “breathe” with sound:

Replace width/height logic with:

audio = op('audio_level')[0] width = int(40 + audio 140) height = int(20 + audio 80)

Now the text field expands and contracts with audio energy.
