Blob duo

Two gradient blobs overlapping and morphing in a slow gooey rotation.

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 = "blobduo")
val p by t.animateFloat(
    initialValue = 0f,
    targetValue = 1f,
    animationSpec = infiniteRepeatable(
        tween(2200, easing = FastOutSlowInEasing),
        RepeatMode.Reverse,
    ),
    label = "p",
)
fun blob(flip: Boolean) = RoundedCornerShape(
    topStart = (40 + 20 * if (flip) 1 - p else p).dp,
    topEnd = (60 - 20 * p).dp,
    bottomStart = (60 - 20 * p).dp,
    bottomEnd = (40 + 20 * p).dp,
)
Box(Modifier.size(40.dp)) {
    Box(
        Modifier
            .size(28.dp)
            .clip(blob(false))
            .background(MaterialTheme.colorScheme.primary.copy(alpha = 0.7f)),
    )
    Box(
        Modifier
            .align(Alignment.BottomEnd)
            .size(28.dp)
            .clip(blob(true))
            .background(MaterialTheme.colorScheme.tertiary.copy(alpha = 0.7f)),
    )
}
