Hello sister, nice question.
Yeah, I know about the Holographs, they are not very simple, since the student needs to have a little familiarity (and some intuition) with math. But it is a wonderful study. Maybe the simplest one is the Unity Holograph. It has much to do with the meaning of ONE, the fundamental number.
But the bulk of this site has to do with the Bible Wheel, a study on how the 66 books are arranged according to the meaning of the 22 Letters of the Hebrew Alphabet (as in Psalm 119). This study is much more simple than the Holographs.
I also enjoy the study on the meaning of the tabernacle. It is a neverending study. Whole books can be written about it. Right now I'm particularly involved with the structure of the Candlestick (Menorah), the most peculiar piece of furniture in the tabernacle.
As for your question about 111 and 1111, the first thing that comes out is that they are all grounded on the Number 1, which is the number of beginnings. See for example the first letter Aleph (Greek Alpha). God said that it means Beginning. The numerical value of the word Aleph is 111! The Number One - the Number of Beginning - thrice reiterated. Since the Reality and our existance begin with God, Aleph is a proper symbol of God Himself. He is ONE. One, One, One. Father, Son and Holy Spirit.
The number 1111 also echoes the foundational feature of the number one. In Psalm 11 we find the expression "the foundations". The numerical value of the corresponding Hebrew word (HaShatuth) is 1111!
