do yo have any idea for this

remember da vinci's model of airoplane was only hypothetical that time.

DARE TO think on such a topic !!!!!!!!!!

consider a problem is given to us to realise this hypothetical situation . what will be your approach


we are to create a television in air . ie we can use the devices on the walls at the max and as needed the screen develops in air and the picture plays on it visible on both sides


present your ideas
a good hypothetical but logical which cant be realized now but seem to be realized in future is awaited with a good paper work(at least in 1000 words ) and will be awarded properly.
Believe it will be a good prize more than expected ever.
looking for the best reply!!!!!
