DNA helix

Two dot strands weaving past each other like a rotating double helix.

Installation

caveui components are copy-paste Jetpack Compose built entirely on Material 3 — there's no caveui dependency to add. Make sure Material 3 is on your classpath (it ships with the Compose BOM), then copy the Usage snippet below into your project.

kotlin

// build.gradle.kts (module)
dependencies {
    implementation(platform("androidx.compose:compose-bom:2025.06.00"))
    implementation("androidx.compose.material3:material3")
}

Usage

kotlin

val t = rememberInfiniteTransition(label = "dna")
val phase by t.animateFloat(
    initialValue = 0f,
    targetValue = (2 * Math.PI).toFloat(),
    animationSpec = infiniteRepeatable(tween(1400, easing = LinearEasing)),
    label = "phase",
)
val c1 = MaterialTheme.colorScheme.primary
val c2 = MaterialTheme.colorScheme.tertiary
Canvas(Modifier.size(width = 48.dp, height = 28.dp)) {
    val n = 6
    repeat(n) { i ->
        val x = size.width * i / (n - 1)
        val s = sin(phase + i * 0.9f)
        val y1 = size.height / 2f + s * size.height / 2.4f
        val y2 = size.height / 2f - s * size.height / 2.4f
        drawCircle(c1, 3.dp.toPx(), Offset(x, y1))
        drawCircle(c2, 3.dp.toPx(), Offset(x, y2))
    }
}
