You can move the points A, B and C (click on the point and drag it).
Press the keys “+” and “−” to zoom in or zoom out the visualization window and use the arrow keys to translate it.
You can also construct all centers related with this one (as described in ETC) using the “Run Macro Tool”. To do this, click on the icon , select the center name from the list and, then, click on the vertices A, B and C successively.

Trilinears a/[(a - b) cot C + (a - c) cot B] : b/[(b - c) cot A + (b - a) cot C] : c/[(c - a) cot B + (c - b) cot A]
Barycentrics f(a,b,c) : f(b,c,a) : f(c,a,b), where f(a,b,c) = a2/[(a - b) cot C + (a - c) cot B]
X(103) = circumcircle-antipode of X(101)
X(103) = Ψ(X(101), X(3))

X(103) = midpoint of X(20) and X(150)
X(103) = reflection of X(I) in X(J) for these (I,J): (4,116), (101,3), (152,118)
X(103) = isogonal conjugate of X(516)
X(103) = complement of X(152)
X(103) = anticomplement of X(118)
