New calendar technology

A follow-up to yesterday's post about calendars. We've started testing a project timeline calendar that looks like a bit like a Gantt chart, which is a newfangled calendar technology (meaning it's a hundred years old, not several thousand—there's not a lot "new" in calendars this century). It has a special jagged red line "right now" feature you'll see below. They key thing is that, like a calendar, time starts on the left and moves to the right. Whenever you need to visually represent time progression that's the best way to go.

Here's an example of it (hat tip to J Atlee). It was used to plan and report on our progress as we performed a multi-day rearrangement of our warehouse floor. The red line, where we're currently at, moved every few hours. Here it shows where we were Day 1 at 1pm (ahead of schedule on the part of the red line that angles a "V" to the right, the rest on schedule):

At 4pm (behind schedule on the part that angles to the left, ahead on the angle to the right, the rest on schedule—also the line is drawn at the chart's 5pm, not 4pm, because they stopped an hour early):
