This screen features a 7000 points flexiScroll with
a soundtrack by Bip played at 25khz oversampled to 50khz (takes about 50%
of CPU). It presents different curves (circles, triangles...). We can create
any type of curves as it is a point by point deformation
This flexiscroll uses an amazing technique by Krag,
different from classic ones, based upon xor operations on letters fronts
