Creating a diamond-like shape, but simplified and organic

→ Starting on a diamond.

→ Making it slightly non-perfect.

→ Connecting dots, irregularly. Remember the initial desire for something neural? Well, we have not forgot about that.

Update on the capital T

→ The previous version was already capitalized but modified: back then we had trimmed the left serif for aesthetics, and primarily to minimize whitespace when left-aligned.

→ This time, we added back a bit of that left tail serif, but kept it short to continue to comply with our idea of a short white empty space when left-aligned.

→ From left to right, the image below displays the original capital T, the updated capital T with a left serif tail, and the lowercase version.

Colors

→ Used green from one of the provided palettes.
→ Using a dark variation of that green for the brand dark ink.
→ Complimenting that with a yellow accent, also selected from one of the provided palettes.

Updated logo mark

"In summary: we polished the capital T, updated the color palette, and redesigned the pictorial mark into an organic, diamond-like symbol that abstractly connects to neural networks.
