During F2L lookahead I often find myself looking at partially hidden corners (with two stickers visible) and hesitating to figure out what they are. Its something I've been trying to improve on, but its difficult to do on a physical cube ... so I decided to make an app for it.

My PB so far: 28.64 (with NOU option set).

I've been wanting something like this for a long time but didn't have the programming knowledge to make it. Thanks.

EDIT: When I have it set to "NOU", sometimes it still gives U corners.

Yup, when you set nou, it doesn't show any cases with U stickers visible, but you may still get corners belonging to the U-layer. I chose to do it like this because it keeps it like F2L lookahead. If you see a corner with no U or D sticker, you need to be able to establish whether or not the corner does in fact belong to the D-layer. These cases are the ones which often throw me off :eek:

Great idea, because if I saw for example Blue and Red, I immediately knew what corner it was. Adding some U corners in there forces me to reconsider.

My cube orientation was Yellow on top and Blue in front.
Neither of the cubies shown are possible solutions for the third color.
The actual solution of the unknown sticker is Red.



This time it is the exactly same case and I chose the right piece and it still says it should be YBR.

First try 24.47
Wow, pretty good .. I'd expect you could probably sub-10 it with a bit of practice. :)
Are you using the keyboard controls ... and did you have any problems with image loading lag?

wow, harder than I thought.
Yup, deffow is for me too :D

Aah, thanks for pointing that out ... I had a hunch something was wrong a few times, but I thought it was must my n00b-ness. Turned out there was an error in a single digit of one of the case tables ... should be fixed now ;)

I know my color scheme fine, but the problem arises when I see, for example, a corner with green and red. How can I tell if the third color is white or yellow?
