This is so creative. Brian Cerveny took some grass seeds and sprinkled them on his keyboard. The end result is a beautiful keyboard lawn.
Watch the video if you are curious to learn about how to plant a lawn on your own keyboard. Make sure you use an old discarded piece as you need to spray water for the green sprouts to pop-up in between the keys.
The original video uses clover seeds and/or the cat grass seeds that they say are available in pet stores. I guess the regular moong dal available in India should do the trick as well.
