He He! Sometimes I even made too complex.
I remember one time that I had to upload a filter, but I could not succeed. Then I found that the reason was because the library had a fixed maximum size for uploading a filter. They changed this setting just for me. (Thanks FF! Many other companies would not change settings for just 1 user).
I also have an old filter. One of the first I made. It was a complex combination of metallic nets and surfaces with a lot of rusted blades dirty of blood. The title was "Infernal Machine". But it was really "infernal", not only for the look. It was a big and complex filter. Still not completed. Maybe one day I will work on it again.
