Hi, everyone.

I would like to create some nice effects in my website's logo. I encountered some pretty logos:



Where can I find tutorials for creating such logos with these letters and colourful squares? I guess this is not very complicated...

Welcome aboard!

There can be several ways to skin the cat.
I can think half a dozen methods for the first image. Some may even overcome the small details that are off on it.
By getting some experience with drawing vectors, you can find the solution you prefer.
To be honest I don't think you will find a tutorial on it. That, for a logo, is anything but pretty.

The second effect with the squares can be recreated with the tiled clones feature and the tweak tool.
Again, those squares are not pixel-fitted, note how the white space in between differs.
Not very complicated, that's right. But by making things relatively fast you can slip on such details that only experience can help.
