I see, but the iPhone apps people often pay for tools they can use to create multiple artifacts. Maybe it'd be best to charge less per creation (like $1) and remove more features from the free one (e.g. animations could expire in 1 day and can't be downloaded).
The reason we don't want to "cripple" the free version is because we have low overhead and can afford to make low revenue at the outset- We'd rather focus on capturing a larger market (though it's always hard to say what the market really is with a new product)
