Update...
v 2 of the mod I previously posted, now with white background versions and a newer ring texture, also fixed the problem of the blocks being blacked out after/during a match... also deleted the cliff textures as there is almost nothing special\cool\unique about what it looks like...
attached is the .zip including the new mod(s), and also a screen shot...
also, laserrobotics, the cliff changes the graphic of the 'cliff' to the left and right of the track...
