Hi guys!
Lately I've been playing around with slimeblocks and sugarcanes, and I've come up with this simple yet very interesting idea: using fencegates for the collection sistem of a sugarcane farm. After a little bit of skinning, this is the design I am presenting you: a fully automatic farm that is fully expandable, can produce up to 500 items per hour in the basic setup and works with slimeblocks. It uses an horizontal layout. Also, I'd say it's quite small and inexpensive: after you've built the main part, It's just a matter of adding dirt, water and a little bit of redstone and rails, but nothing too expensive.
I recorded a video with a tutorial, so if you want to see more you can just watch it.
I'm putting a world download as well as some screenshots of the build.
Feedback is welcome!

BTW, I realized how long it takes to render and upload videos (36hrs just for uploading with my poor ADSL... )
