While, we can design and we do design and deliver 'new' creative activities. The 'creativity' in these activities does not emerge from the 'newness' of the activity itself, neither does it emerge from the 'complicated' nature of anything that we put forth. It emerges from the child being able to look at something 'existing' with a 'new' pair of eyes, him/her being able to observe a phenomena they were previously oblivious to. In fact, them being able to overcome the pressures placed by the society to forget their child-like curiosity and help them be 'curious' all over again!
if an activity is able to achieve this or even partly this, it is a 'creative activity' in itself!
