Sure thing....here's my method.
1. Top-4 Corners Correct-Color-Up (Orientation but not Placement). (Free style)
2. Bottom-4 Corners Correct-Color-Down. (One of several algorithms)
3. All 8 corners correct. (But I don't usually align them).
4. Key Step: I build the Top edges in such a way that I then do a transform on them....to get the middle layer.
A. It's called railroad tie....because it's 3 strips.
So the Green Yellow and Blue Yellow edges...you can't see. But by doing it this way....you can do a half-turn on Red & Orange and D' (Blue side)...and get to....
Then you do the top edges, and then the bottom edges.
I created this method originally....to make it easier to teach someone with fewer algorithms.
Back in the day....I kind of used only a couple different algorithms (repeated) to get the bottom 4 corners.
I would build the top 4 corners....then the bottom 4 corners. (replace that with Varasano's method later on).
I basically did one move from different directions (a few times total) to get the bottom 4 corners in place and in orientation.
Then...build the top (railroad tie)....build the bottom....and then one three-cycle...(also repeated)....to finish it off.
I use to say....if someone could do the top layer easily (in a minute or so)....that I could teach them the whole cube in
about an hour. (And they would be in about a 5 minute range at tops).
Ok...feel free to ask any questions.
So....it looks like I only have 2 people to rule out.
And...one I found on facebook....and Linked-in....and I think she's one year (or two) younger than I am. (That's Donna Hays).
And that leaves David Faust who seems to have only participated in one competition.
Thanks for everyone's help.....I'm doing a friend request (and message) to Donna....and hopefully she will reply.
Not sure how to find more info on David.
Thanks again all.
Although I'm very busy.
I'm an indie-game-dev that's created my own original IP (called Clutter) and I'm working on my 11th game in that series.
