What software do yall use to make these drawings? They all look great and seem to have more detail than most of the other sites ive seen. I saw on the other post where someone was asking about a specific style? and was told to try http://www.apophysis.org/.

I am more interested in the more fixed designs if that makes sence. They look like a defined object and have a personal touch. Say like the windows or linux logo for example. Its defined and not so abstract if thats the right word.

Thanks.
