Thanks for the nice up-date of the Guisecliff Wood motif, Rich!
I only had an old photograph, taken by Maarten van Hoek.
Square motifs are rare in British rock art indeed and Hob's remark of the rounded corners makes sense.
There are old-fashioned TV's with rounded corners but also "modern" flat-screens:

One is tempted to count the cups in the squares but, as we all know, counting and measuring hasn't brought any closer to understanding so far.
I will add some more panels to the collection on BRAC today.
Please let me know if you can think of newies. Thanks!
Cheers,
Jan
