Randomizable value properties are a mess, there is a lot of minimumValue (random and animation have it) properties and a value.

This must be simplified in a simpler property type:

value: T | IRange<T> // T is a generic type

and the new IRange interface is made like this:

interface IRange<T> {
    min: T,
    max: T
}

If you want confetti to blow out from a button, it'd be good to be able to pass an element.
