Hi, here my proposal for you. I wanted simply and clever to imply the meaning of the word abstract into the logo. I used small dots/pixels to make an abstract representation of the "a" letter. I chose "a" for two reasons, 1] it is repeated so you have already the image of the normal "a" while you are reading the logo, making the second one easier to recognize. 2] It is the initial of the word "abstract" and also the first letter of the alphabet.
I have made a bigger standalone "a" to see how it works as an emblem by itself
Colors and anything else can be changed if asked, of course.
