NoSleep or No Sleep Nigel is a music professional who wrote the Oolite title screen theme, and performed the Oolite docking music version of the Johann Strauss II "An der schönen, blauen Donau", Op. 314 ("The Blue Danube"), using a (simulated) glass harmonica.

He is believed to have been the very first Oolite playtester, the nascent project brought to his attention by JonnyCuba in the spring of 2004, but edged ahead of his friend by a few hours in the all-time chronology of playtesters.
