Thanks for subscribing to LL, here's what to expect…

Hello! I’m Callum. Thank you for subscribing to The Littoral Line—an email letter about creativity, design and complexity through the lens of attention and interfaces.

Littoral as in the edge of things, like tidal zones. Line as in symmetry, like the alignment of metaphor.

Outside of Substack, I have a website that showcases my trade (I design and build websites). Although it’s been paid no time the past few years, I do recommend these two articles as gestalt ideas that are a base for my work:

• The instantaneous language of beauty

• The matter of taste

Thanks again, and please tell a few friends if you feel like it.

Some housekeeping...
