I was hacking around on the JavaFX 2D Tutorial application when I noticed a bug in the ImageView class. Setting antialias: true actually disables antialiasing; and setting antialias: false enables antialiasing.
antialias: true

antialias: false:

I went back and applied this to the sellmic.com clock that I've been hacking on. You can launch the clock with antialiasing enabled below.
