The device is passing through OSCAR currently, and is somewhat different than the original concept. The commentary includes making sure to use a period depiction of the letter 'pi', nad making sure that the hourglass is not transparent (in the emblazon below it is argent, in other emblazons it picks up blue where the argent is in the sand areas, which is problematic.)

The color structure works great. However, while you can incorporate pi in a heraldic design, unfortunately the abstract symbol cannot be the _only_ charge.
Additionally, pi as a symbol for the ratio between circumference and diameter only dates back to the mid-18th century.
