try (number->string).

(delta) should return smaller values, the time in seconds since the last

i'm not sure if you wanted to do this, or something else.

this should rotate the cube around the vertical x-axis. maybe you 
rotated the camera. try (hint-origin) which shows the x-axis as a red 
line segment if you are unsure.
