Another slo-mo PLL iPhone video? Maybe this will become a series, after all….
H was the very first one-look PLL I learned. It forced me to learn M slice flicks for the four M2′ combos, each of which I executed as two single M’ flicks. Soon thereafter I learned double-M’ flicks (pulling back to front across the bottom with my ring then middle finger), allowing much faster execution. Although I also learned double-U flicks, I couldn’t get my right hand fingers into position for those doubles while holding the cube in a way that allowed for the double-M’s. So, I would do double M’s and paired single Us. I eventually learned the M-based U Perms which relied on a mix of U and U’ as shown in this slomo video. Last week, a lot of folks commented that my Ub push/pull finger trick on the U layer was innovative.
What if I used that same trick for the H Perm, like so:
M2′ U’ M2′ U2 M2′ U’ M2′
Turns out, it works quite well.

: Maru CX3)
My left hand index finger executes the U’ by pulling left to right across the front. That puts the index finger in a position to push right to left for the U2, and in a position to do the second U’ like the first. The only challenge was that muscle memory kept telling my left hand to move the M layer as though I was doing a Ub perm. A couple days in, the synapses have adapted and separated the two. My execution is good, but there’s speed to be gained.
It seems that iPhone 6 slo-mo videos are all the rage these days. Why not jump on the bandwagon? No doubt slow-motion is useful for teaching new algs and finger tricks. Here’s a quick proof of concept based around my execution of the U-Perms:
Not bad for a phone, eh? Although this was shot under the same light as my other videos, it does appear darker and noisier (with the sensor trying to compensate). It seems that the 240fps frame rate does drop the total light processed by a good 50%. I’ll need to blast it with light next time.
I have an ambitious plan up my sleeves for a video based around the slo-mo feature. But with the clunky workflow (needing to pass the video through the iMovie app before offloading for editing in FCPX), it might be a while before I find a solid uninterrupted block of time for it.
P.S. I just recorded a similar video for the Nb Perm (z D’ (R U’ R2′) D (R’ U D’) (R U’ R2′) D (R’ U R) z’):

Maybe I’ll consider a series of these….
Following up on my V Perm post, I thought I’d give another go at doing a multi-cam of a couple other long PLLs — the two Rs:
z D’ R2′ D (R2 U R’) D'(R U’) (R U R’) D (R U’) z’
It’s not weird to have a favorite algorithm, right? I mean, look at unboxing or review videos, and each cuber seems to have a go-to move. For a while now, mine’s been the V Perm — the PLL that (a) swaps opposite corners and (b) swaps the adjacent edges next to them. I hated the V Perm, as I first learned it: R’ U R’ d’ R’ F’ R2 U’ R’ U R’ F R F. That algorithm was clunky, without a good flow.
Enter jskyler91, who posted this “non-standard” V Perm execution, which flows smoothly with no re-grips:
z D’ R2′ D (R2 U R’) D’ (R U’) (R U R’) D (R U’) z’
Since it’s one of the more complicated executions in my repertoire, I thought it would lend itself to a multi-angle video. I did something similar, when I was still learning the algorithm, and I wanted to update it:
It’s been a little while since my last post — that monster parity article that still has my head hurting. I’ve got a couple things in the works, but I put them aside when I got a Maru CX3 the other day. I’m really impressed with the cube, and I found my turn style and speed improving with it. On a whim, I thought I’d give a sub-60 PLL Time Attack another go with the CX3. I came awfully close, at 60.65 seconds. Here’s the video (with apologies for some of the out-of-frameness):
