It’s an easy walk from the apartment I lived in in ‘85-‘86; I shopped at the Safeway there, bought caramel corn there. Spent wonderful times with my father there in the 70s. Malls are an expiring form but this one takes something with it when it goes.

From this day in 2021: My nephews were curious about Final Fantasy after seeing a Moogle I drew and I described Chocobos as looking "kind of like Big Bird" so then I had to draw it.

My favorite ludicrous New Yorker style is that they print initialisms in full caps but acronyms (initialisms pronounced as words) in small caps, so in the days of CD-ROMs, they'd write the word like this:
CD in full caps followed by hyphen-ROM in small caps.

We've just been having a look through a sweetly presented digital version of the Jurassic Park novel for the Apple Mac released in 1991. In the preface, Michael Crichton talks about how enthusiastic he is for the format and how it allows him to add sound effects and animations.
A snap of Voyager Expanded Books release of Jurassic Park's original novel with a silhouette of a T-Rex skeleton and the book name. 

"This book belongs to Sasha T. Rex."A snap of the book presentation with a kindle-like feel. We were searching for when someone says '"Welcome... to Jurassic Park."Author's Preface, where MC discusses his philosophy for the digital releases.

Worms is part of a genre of “artillery” computer games that we thought went back to the 70s, until we discovered it actually went back to the 60s. In this thread, Kevin Bunch reveals he’s unearthed long forgotten footage of the lost game that started it all.
Example of an artillery game from the Wikipedia article on the topic.
