Khalid Qasim, originally from Yemen, was released in January 2025 after spending 23 years at Guantánamo. He frequently experimented with the limited range of artistic materials Guantánamo afforded; he has painted in coffee and on sand and gravel gathered from the prisoners' exercise yard, and has created sculpture from various discarded materials, including MRE boxes.

"This is the Hall of Enlightenment. As represented by the stairs, the only way to establishing a strong foundation of knowledge is by one step at a time. As depicted by the clock, time is an essential element therefore every moment must be cherished. One must not wait to acquire knowledge as time has already begun ticking. The flat top indicating the infinity of knowledge. The more you attain the more you desire. 1:30 AM Fri Sep. 9, 2016, K 242, Guantanamo, Cuba"
