While inspecting
a new crop picture at Sugar Hill on August 1, the noted crop-circle
researcher Janet Ossebaard suggested to me that its "18 cubes" might represent a near-future date
of August 18, as likewise suggested in an earlier crop picture from
East Field by phase cycles of the Moon. I replied that those mysterious
crop artists seldom use modern calendar schemes; and that one would
have to figure out what all of those strange "cube" symbols
were intended to represent, before being able to interpret
the new picture with any confidence.
But after making
a careful study, it seems she was correct! In ancient times,
many different cultures on Earth would construct "cube
sundials" in order to tell hourly time during different parts
of one full day. Four or even five different vertical sundials
would be inscribed onto different faces of a stone cube:

"It used
to be traditional to place four sundials on the sides
of a tower in order to tell time of day. Alternatively,
a pillar could be erected to hold a a cube of stone,
and four sundials could be inscribed thereon." (en.wikipedia.org/wiki/Sundial).
Three weeks earlier at Toot Balden, we saw their definition of a
cube sundial as one that would keep daily time in units of 36 x
10 degrees by the sun's shadow, or equivalently 36 x 40 minutes:

Then on August 1 at Sugar Hill, they drew another picture that showed
18 cube sundials at its centre, surrounded by four rings of 36 smaller
time-units on its outside:

Since the latter
picture appeared close to midnight on July 31, its message would
seem to be that "only 18 days remain until
some significant event on August 18". But what could be happening
on August 18, 2007 apart from a conjunction of Venus with
the Sun?

Well, we only
have to wait two weeks to find out! That date was first indicated
in crops by a Mayan Sunstone at Wayland's Smithy in 2005. There
a binary-hexadecimal number of 14-5-11 was used to specify August
16-19, 2007, once translated from the ancient Mayan 52-year calendar
into our modern scheme. Then at Wayland's Smithy in July 2006,
the longest of several "astronomical rays" showed
a 7 x 8 grid at its end, in order to say 56 weeks or August 2007.
Finally one month ago at East Field, four successive phase cycles
of the Moon seemed to "end" on August 18.
Personally I would not worry! The most important thing to hope for
would be a significant verifiable event, where those crop artists
use their wormhole technology to predict something important in
advance, and thereby convince a majority of Earth scientists that
modern crop pictures are real.
