The main stay of this ceremony was the 'aerostat' or as the door-darshan guy put it 'dunya ka sub say bara gubara'
The fact that the cost of this blimp is 1/3 of the entire cost of the ceremony does reflect rather poorly on the opening ceremonies.
This blimp or 'aerostat' has actually been brought on lease from an Italian company K-Event and reportedly the He gas came from Russia

Through out the ceremony there were no 'precision displays' that made you hold your breath and the special affects were rather ordinary.
Rest of it was a bit too Bollywoodish with songs and extras with belly-exposed women.
The opening ceremonies are actually very good reflection on what is india today that on the outside great attempts are made to make is aprear shining but a deep look will reveal that the hype is lot more than reality.
