Describes a horizontal sundial (SRN 3936) located in a garden memorial at Ahakista, West Cork, Ireland, dedicated to those who died in the 1985 Air India flight explosion. Designed by Ken Thompson and delineated by Owen Deignan, the dial features the motto 'TIME FLIES...' and a plaque giving the Equation of Time.

Describes a modern horizontal ‘Flat Sundial’ installed in 2011 outside the Nautical Museum of Crete in Chania. The pedestal provides Equation of Time corrections in six languages, though the author notes the original elegant gnomon appears to have been damaged and replaced by a simpler version.

This article focuses on the additional informational elements, or "furniture," found on vertical sundials beyond just hour lines. It uses the Queens' College dial as an example of a dial rich in such information (altitude, azimuth, zodiac, sunrise time, day length). The author explains how to calculate and display various furniture types, including equinox and solstice declination lines, altitude and azimuth lines, and monthly declination lines, all based on the shadow cast by a "nodus" on the dial. The methodology involves transforming the vertical dial to an equivalent horizontal dial for simplified calculations and discusses the practical aspects of displaying such data.
