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 f(a,b,c) : f(b,c,a) : f(c,a,b), where f(a,b,c) = (1 - cos A)u(a,b,c), where u : v : w = X(1280)
Barycentrics af(a,b,c) : bf(b,c,a) : cf(c,a,b)
X(1477) lies on the circumcircle and these lines:
1,1292 55,1293 56,101 57,100 99,1434 108,1435 108,1435 109,1407 110,1412 738,934 919,1416 1308,1319
X(1477) = X(672)-cross conjugate of X(57)
X(1477) = cevapoint of X(56) and X(1458)
