Directly left of School Room Pillar, climb the low angle ice for 10-15 feet, then proceed up a small rock seam to an overhanging icicle. You can climb up the dihedral behind and past the hanging icicle and then up and behind it for a variation.
The climb is located on the rock face facing up the canyon directly right of 'Rithmitic and directly left of School Room Pillar.
A good top rope, set up either on School Room Pillar (anchor #2) or 'Rithmitic (anchor #3). Rappel down and add a directional right above the overhanging icicle so your fall is good.
