La Marzocco Leva: Reimagining a lever-actuated espresso machine [pdf] (lamarzocco.com)

The Leva incorporates lessons from the Strada’s pressure profiling (http://profileeditor.lamarzocco.com/files/strada_ep_guideboo...) and recording, Web-based editing, and replay (http://profileeditor.lamarzocco.com/files/profile_editor_hel...). From the PDF:

> Live pressure visualization

> The Leva X is equipped with dedicated graphical displays for each group. The displays provide live visualization of pre-infusion pressure, extraction pressure, and time throughout the course of the shot.

> After the coffee has been delivered, the extraction curve and parameters are visualized on the displays as a graph. The barista has the ability to overlay past visualizations, saving up to four graphs for each group, as guides for future extractions.
