Join Luke in his odyssey to regain his health after a devasting bout of Meningitis, and to understand and accept its mysterious legacy -synesthesia.

For some it simply means that when they think of a day of the week, they are bombarded with sensations of a particular colour ... For others, life is a kaleidoscope of mixed sensations ... people with synesthesia can open up the endless world of human imagination and that, I think is the most amazing world of all.
