Design a slider widget with animation

We are looking for a slider widget that will be used to leave reviews in an app. It is is a slider that changes as you drag it across. It will be used to leave a review. So, if you drag it to the right it will change the background color of the widget as well as an emoji to show how happy, or unhappy you are. We would be open to seeing variations on this, similar to how instagram has an emoji that change in size and emotion as you move a slider (if a slider was added to a story). We then want it so if you swipe down on the slider, it will spring up a camera into view. This is the more complex part - we want a visual indication somehow that if you drag down it will bring the camera into view. A possible solution would be using a curve that follows your finger as you drag to indicate that if you swipe down an action will happen. The camera should spring up - so the view should pull down slightly and then the camera should slide (spring) up into view. For delivery, we want: * static concepts on some variations * after making a decision, we will want 1+ animated visuals that we can then build from
