logitech pop keys

Seeing this Logitech POP Keys keyboard, I find myself wishing so many things in life could be simplified this way. For eating, we could draw a symbol of a meal; for writing, a pen; for sleeping, a person on a bed; for happiness, a smiling face; for sadness, an ugly face; for love, a little heart… All of food, clothing, shelter, and travel could be expressed in full.
