This Sunday's Pearls Before Swine comic was also something related - you can see that comic here.
Hello, from the future..
Dear me, today I recalled a memory -
Feeling delightful, and fearful of a future unknown
I buried this time capsule for older-me
On a day that now seems long gone.
With my faithful pen, I sit down to write
As your(my?) grand kids play outside;
For now, I let the capsule be -
Be someone else’s discovery.
Dystopian it is not
nor a green paradise
nor is it a scene from the Jetsons yet
(The trip to Mars – yes, did succeed!
A story for another day, it is)
But know that we did right
Going green and all that
Certainly made our future bright;
Food forests are the theme of the day
and we still have flowers in May,
While CDs and desktops
Are a thing of the past,
The future, well,
I am having a blast!
