zalgo finally brings support for Zalgo text to Go.

package zalgo_test

import (
    "fmt"
    "github.com/kortschak/zalgo"
    "os"
)

const invoke = `To invoke the hive-mind representing chaos.
Invoking the feeling of chaos.
With out order.
The Nezperdian hive-mind of chaos. Zalgo.
He who Waits Behind The Wall.
ZALGO!
`

func Example_1() {
    z := zalgo.NewCorrupter(os.Stdout)

    z.Zalgo = func(n int, r rune, z *zalgo.Corrupter) bool {
        z.Up += 0.1
        z.Middle += complex(0.01, 0.01)
        z.Down += complex(real(z.Down)*0.1, 0)
        return false
    }

    z.Up = complex(0, 0.2)
    z.Middle = complex(0, 0.2)
    z.Down = complex(0.001, 0.3)

    fmt.Fprintln(z, invoke)

    // Output:
    // Eternal happiness.
