I'm very sorry to hear this. I liked his podcasts and his writing here and had been wondering how he was doing.
Walker's creations gave me food for thought the past few years. I related to his passion and anger about the marginalization of pwME. It was because of Walker I started listening to Nico's solo albums based on a blog post he wrote about her. I also loved the song "Frozen Warnings" --where he got his username from.
I am sorry for the loss his family and friends are suffering.
What a cruel illness.
"Into numberless reflections
Rises a smile from your eyes into mine
Frozen warnings close to mine
Close to the frozen borderline
Over railroad station tracks
Faintly flickers a modest cry
From without a thousand cycles
A thousand cycles to come
A thousand times to win
A thousand ways to run the world
In a similar reply
Friar hermit stumbles over
The cloudy borderline
Frozen warnings close to mine
Close to the frozen borderline"
