I want a clean looking logo, nothing too fancy. Here are some important points:
**In all cases, no matter what, I want to use a clean font similar (in terms of font, closeness of letters, and bolding) to uploaded design number 1. And I want to see designs that fall in one of the following categories:
1. Where the name 64x bio (font consistent with above) is next to an icon similar to some of the designs I uploaded. In this case, I'm interested in icons that look like a cube with one piece missing. Some ideas are uploaded. Some things I like are a) icons that have more white space, where it doesn't look too black when scaled down, b) simpler icons.
2. Where there is no icon, and it only says "64x bio" or "64x" (font consistent with above) and where there is some design on the x. But in terms of a design on the x, I'd like to not change the font of the x, but just small features about it. For example, here are some ideas:
a) I'm interested in potentially a design where the x has a rainbow gradient on one arm, or even where there are pixels that are rainbow colored. Here's an example of a rainbow gradient, but in this case it's inside the icon and not the letter x like I'm describing: recursionpharma.com
b) Where the x has designs within it, like pixels or mini parallelograms making up the shape of the x, where it's just black and white outlines of the pixels, without color, or maybe even with color. Here's an example of what I mean by pixels or parallelograms filling out the outline of a shape, but in this case the parallelograms are inside the icon, and not the letter x like I'm describing: recursionpharma.com
c) Where the x lacks any color but has certain cut outs on it, like maybe a chunk taken out or some kind of other feature to it that's interesting, without changing the font too much. Here's an example: arsenalbio.com
