I found some info for you which helps with my basis. All from Coptic Church.
Please note these are small excepts from a larger article:
The art of making Orthodox icons follow certain symbolism that carries a
aristic style of iconography varies a little from one culture to another, all
Orthodox icons have the same meaning, usage and symbolism (this includes the
Eastern Orthodox Churches; Greek, Russian, Serbian, Bulgarian, ... etc, as
well a the Oriental Orthodox Churches; Coptic, Armenian, Syrian, Ethiopian,
Therefore, the leaders of the Early Church permitted the use of
religious pictures (icons) because the people were not able to assimilate
Christianity and its doctrine unaided by visual means. Therefore, these
presentations aided the faithful in understanding the new religion and, at
same time, illustrated it.
In conclusion, icons in the Orthodox tradition are not to be taken as art for
art's sake but rather, they are to be used as windows into spiritual world,
designed to help us achieve a prayerful mind set and lead us into a life of
prayer and contemplation. The interested reader might want to check the icons
scanned and stored in Copt-Net Archives.
The above are just a small sample of what the Coptic Church teaches and you see that the image written (painted) in the Icons are to be venerated for worship. The Icon itself is NOT to to be used as an object of worship or a decoration for arts sake. Thus the blinking lights can imply that the Icon itself 'in-the-physical' has some center of attention or significance even though this may not be intended and thus goes against the central purpose of 'why' we use Icons in the Orthodox Church.
The way the Icon was used for father Mina was understandable but rather liberal. The Coptic Church nor the Orthodox Church in general teach that the holy images can be used the way 'we want'. such as adding blinking lights.
We have to be careful with the Holiness of the Orthodox tradition ..we must protect its innocence and holy intent. Doing this leaves us little room for levity or creativity.
You should read the whole article yourself.
