got my mods under 140, yay.

u/BriSeven

although this 151 has a nicer effect. c.width|=c.style.filter=blur(${1-S(t*6.3)*4}px)contrast(9 x.scale(80,99) for(i=2;i--;x.fillText(~~v%10,9,9))x.fillStyle=R(0,v=t+i/2,0,T=.5-C(v*6.28))
u/BriSeven

even more appealing c.width|=c.style.filter=blur(${.5-S(t*6.28)*12}px)contrast(12 x.scale(80,80) for(i=2;i--;x.fillText(~~v%10,9,9))x.fillStyle=R(0,v=t+i/2,0,T=.7-C(v*6.28))
