"nothing new under the sun" - so the saying goes - and this is very true of all design in some form or other - however a fresh interpretation of an old theme makes things interesting. as designers we always want affirmation for concepts. however its in some way all been done before.
what the lesson is for me anyway - is to experiment with conceptual age old ideas and improve ways of communicating these concepts using sketch - that is always exciting and fresh.
for this i have only paper and a pen - one does not need much more than these things to have a great time.
