What I Need...

... is a good pair of shoes for DDR/ITG/PIU, with decent grip on the pad.  The ones that I have get extremely slippery on the pad with dust or dirt (like the ITG machine at Santa Cruz Boardwalk).

I miss my old shoes. ;_;

Eyes

Yay

2sin−1(sqrt(2+(1−P)cos(φ1+φ2)−(1+P)cos(φ1φ2))/2)

where P=cos(θ1θ2).

Phew.

Edit:

cos−1(cosφDcos2θA−cosφSsin2θA)

where φS=φ1+φ2, φD=φ1φ2 and θA=(θ2θ1)/2.
