We had to make this 6 tier wedding cake recently and we decided to film the entire (90%) process from conception to attending the actual wedding. It was an especially unique project because the cake was made on the Gold Coast (QLD, Australia), and flown to Adelaide (South Australia). It was a huge cake that needed to travel a huge distance (2000kms).
Its a fairly long video but if you have some free time, see how Serdar Yener did it!
